It seems like you can either serve money or God, love one or the other and your eye can be evil in that way
For example,
Mat 6:22 The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.
Mat 6:23 But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
Here is the context of the same
Mar 6:24 No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other.
Ye cannot serve God and mammon.
Here is where the single and evil eye is
Prov 28:22 He that hasteth to be rich hath an evil eye, and considereth not that poverty shall come upon him.
Light and darkness as it relates to our brethren also
1 John 2:9 He that saith he is in the light, and hateth his brother, is in darkness even until now.
Same shown here similarly of the evil eye, in the sense of selfishness,
Duet 15:9 Beware that there be not a thought in thy wicked heart,
saying, The seventh year, the year of release, is at hand; and thine eye be evil against thy poor brother,
and thou givest him nought; and he cry unto the LORD against thee,
and it be sin unto thee.
The question of the love of God dwelling in such a one here
1 John 3:17 But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?
James 4:17 Therefore to him that knoweth to do good,
and doeth it not, to him it is sin.
1 John 3:18 My little children,
let us not love in word, neither in tongue; but in deed and in truth.
Which you can see the same principal play out in them which were covetous here
Luke 16:13 No servant can serve two masters: for either he will hate the one, and love the other;
or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
Luke 16: 14 And the Pharisees also, who were covetous, heard all these things: and they derided him.
They esteemed abomination
Luke 16:15 And he said unto them Ye are they which justify yourselves before men;
but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God.
These guys deriding Jesus on this thing, and justifying themselves as well, would seem to indicate the same sort of perverse disputings found here as well
1 Ti 6:5 Perverse disputings of men of corrupt minds,
and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.
Prov 28:22 Hethat hasteth to be rich hath an evil eye, and considereth not that poverty shall come upon him.
Prove 23:6 Eat thou not the bread of him that hath an evil eye,
neither desire thou his dainty meats:
Mark 7:21-23 For from within, out of the heart of men, proceed evil thoughts, adulteries,
fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man.
The lense seems more about having a love of money, or love of the world or the things of the world verses a love of God in respects to that eye, and the Pahrisees loved money (not God)

"16:10-13.
He that is faithful in little, is faithful also in much; and he that is unjust in little, is unjust also in much. If therefore you have not been faithful in the unrighteous mammon, who will give you the true? And if you have not been faithful in that which is another's, who will give you, that which is your own? No servant can serve two lords: for either he will hate the one, and love the other: or he will honour the one, and despise the other. You cannot serve God and mammon.
THE most distinguished and experienced teachers, when they wish to fix any important doctrine deep in the minds of their disciples, omit no kind of reasoning able to throw light upon the chief object of their thoughts; at one time weaving arguments together, at another employing apposite examples, and so gathering from every quarter whatever is serviceable for their use. And this we find Christ also, Who is the Giver unto us of all wisdom, doing in many places. For oftentimes He repeats the very same arguments upon the subject, whatever it may be, that the mind of those who hear may be led on to an exact understanding of His words. For look again, I pray, at the purport of the lessons set before us: for so you will find our words to be true. "He that is faithful in little," He says, "is faithful also in much: and he that is unjust in little, is unjust also in much."
But in what way men may become faithful, the Saviour Himself next taught us: and I will explain how. A certain Pharisee besought Him to eat bread with him on the sabbath day, and Christ consented: and having gone there, He sat down to meat: and there were many others also feasting with them. And none of them by any means resembled men who possessed nothing, but, on the contrary, they were all persons of distinction, and great haughtiness, and lovers of the foremost seats, and thirsting after vainglory, being clothed as it were in the pride of wealth. What then said Christ to His inviter? "When you make a dinner or a supper, call not your friends, nor your brethren, neither your kinsmen, nor your rich neighbours, lest they also invite you again, and a re-compense be made you. But when you make a feast, call the poor, the maimed, the lame, and the blind. And you shall be blessed, because they cannot recompense you; for you shall be recompensed at the resurrection of the just." This then I think is a man's being faithful in little, that he have pity upon those who are in need, and distribute assistance from his means to such as are in extreme distress. But we, despising a way thus glorious and sure of reward, choose one dishonourable and without reward, by treating with contempt those who are in utter poverty, and refusing even sometimes to admit their words into our ears; while, on the other hand, we luxuriously provide a costly table, either for friends who live in pomp, or for those whose habit it is to praise and flatter, making our bounty an occasion for indulging our love of praise. But this was not God's purpose in permitting us to possess wealth. If therefore we are unfaithful in the little, by
|514 not conforming ourselves to the will of God, and bestow the best portion of ourselves upon our pleasures and our boasts, how can we receive from Him that which is true? And what is this? The abundant bestowal of those divine gifts which adorn man's soul, and form in it a godlike beauty. This is the spiritual wealth, not that fattens the flesh, which is held by death, but rather that saves the soul, and makes it worthy of emulation, and honourable before God, and that wins for it true praises.
It is our duty therefore to be faithful unto God, pure in heart, merciful and kind, just and holy: for these things imprint in us the outlines of the divine likeness, and perfect us as heirs of eternal life. And this then is that which is true.
When therefore any are unfaithful in that which is another's, in those things namely, which are added unto them from without, how shall they receive that which is their own? How, that is, shall they be made partakers of the good things which God
|515 gives, which adorn the soul of man, and imprint upon it a divine beauty, spiritually formed in it by righteousness and holiness, and those upright deeds which are done in the fear of God.
And that it is a thing impossible for one and the same person to divide himself between contraries, and still be able to live blamelessly, He shows by saying, "No man can serve two lords: for either he will hate the one, and love the other, or he will honour the one, and despise the other." And this indeed is a plain and evident example, and very suitable for the elucidation of the subject before us. For that which follows is, so to speak, the conclusion of the whole argument: "for you cannot serve God and mammon." For if, He says, a man be a slave of two masters, of diverse and contrary wills, and whose minds are irreconcilable with one another, how can he please them both? For being divided in endeavouring to do that which each one approves, he is in opposition to the will of both: and so the same person must inevitably appear bad and good. If therefore, He says, he determine to be true to the one, he will hate the other, and set him of course at nought. It is not therefore possible to serve God and mammon. For the unrighteous mammon, by which wealth is signified, is a thing given up to voluptuousness, and liable to every reproach, engendering boasting, and the love of pleasure, making men stiff-necked, the friends of the wicked, and contemptuous: yes, what base vice does it not produce in them that possess it?
But the goodwill of God renders men gentle, and quiet, and lowly in their thoughts; long-suffering, and merciful, and of exemplary patience, not loving lucre, nor desirous of wealth, content with food only and raiment, and especially fleeing from "the love of money, which is the root of all evils:" joyfully
|516 undertaking toils for piety's sake; fleeing from the love of pleasure, and earnestly shunning all feeling of wearisomeness in good works, while constantly they value, as that which wins them reward, the endeavour to live uprightly, and the practice of all soberness. This is that which is our own, and the true. This God will bestow on those who love poverty, and know how to distribute to those who are in need that which is another's, and comes from without, even their wealth, which also has the name of mammon."
