Just insert "sabbath" (which isn't there)
I can and mentally do such word 'substitution' as that is allowed in God's method of interpretation. For instance:
Rev_1:16 And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
Rev_2:16 Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.
Rev_19:15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
Rev_19:21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
What is that symbol, and meaning? Simple substitution:
Heb_4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
Psa_149:6 Let the high praises of God be in their mouth, and a twoedged sword in their hand;
Isa_49:2 And he hath made my mouth like a sharp sword; in the shadow of his hand hath he hid me, and made me a polished shaft; in his quiver hath he hid me;
Psa_55:21 The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.
Eph_6:17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
The Bible teaches word substitution, even by example and precept, line upon line (Isaiah 28:10,13).
Therefore, knowing that Isaiah 58:13, etal. teaches that the seventh day, the sabbath of the Lord my God is "the Lord's ... day", I may rightly place the words there, and the "scripture ...not be broken" (John 10:35).
and stop worrying if it makes a sliver of difference.
Oh, I am not worried, and that you presume to know why I have placed the thread and OP as I have speaks volumes. I do not move in fear, but in faith and love. Feel free to consider this sermon:
The difference is clear, between right and wrong, truth and error, obedience and sin.
Rom_6:16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
By grace, John obeyed the word; I also in the same obey the word. What do you do?
The Ten Commandments (Exodus 20:1-17) are God's own character in written transcript form, see Exodus 33:12-23, 34:1-9, 20:5-7.
No game changer or error either way.
Oh, the difference is as great as light versus darkness, good versus evil, righteousness vs sin.
I agree with the standard of judgment in scripture:
Joh_12:48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
You see, "the Lord's day" deals with the "Lord" (Jesus) of that day. Turn from it, and thus turn from Him, by saying not thy will (Psalms 40:8) be done O Lord, but my will be done.
For there is that on this earth, even at present which thinks to change "times" and "laws" of the Most High God, and it doesn't have to be a system, but also applies individually:
Dan_7:25 And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
When God says, "this ...", they say, "that ..." and so cannot "Amen" God as His image and likeness, for out of the abundance of the heart the mouth speaketh, and are the issues of life, and they show by their denial of what is written, that the seed of another is planted there, rather than the seed planted by God.
Rev 14:6 And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,
Rev 14:7 Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters. [Exodus 20:11]
Rev 14:8 And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication.
Rev 14:9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
Rev 14:10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
Rev 14:11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
Rev 14:12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
Notice, the same John:
1Jn_2:4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
Rev_21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Did you notice the difference in "images"? Do you reflect the lovely Jesus:
Luk 4:14 And Jesus returned in the power of the Spirit into Galilee: and there went out a fame of him through all the region round about.
Luk 4:15 And he taught in their synagogues, being glorified of all.
Luk 4:16 And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.
Luk 4:17 And there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written,
Luk 4:18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,
Luk 4:19 To preach the acceptable year of the Lord.
Luk 4:20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him.
Luk 4:21 And he began to say unto them, This day is this scripture fulfilled in your ears.
Or do you reflect the "man of sin" [1 John 3:4], who thinks to change God's times and laws. Only you, by studying God's word and comparing yourself to its right and true standard, will you be able to answer that question correctly.
You judge by 'your' standards, rather than God's standard in His word. It was already cited that "every word" is important, and that no one ought "add" or "subtract" from any of it, and that man must speak according to "the Law" and "to the testimony", otherwise there is "no light" in them. What you judge as 'flyspecks', God has magnified above all his name:
Psa_138:2 I will worship toward thy holy temple, and praise thy name for thy lovingkindness and for thy truth: for thou hast magnified thy word above all thy name.
Isa_42:21 The LORD is well pleased for his righteousness' sake; he will magnify the law, and make it honourable.
