Well then you must explain
Verses like this:
Ezra 9
1 Now when these things were done, the princes came to me, saying, The people of Israel, and the priests, and the Levites, have not separated themselves from the people of the lands, doing according to their abominations, even of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.[SUP]2 [/SUP]For they have taken of their daughters for themselves, and for their sons: so that the holy seed have mingled themselves with the people of those lands: yea, the hand of the princes and rulers hath been chief in this trespass.
[SUP]3 [/SUP]And when I heard this thing, I rent my garment and my mantle, and plucked off the hair of my head and of my beard, and sat down astonied.
[SUP]4 [/SUP]Then were assembled unto me every one that trembled at the words of the God of Israel, because of the transgression of those that had been carried away; and I sat astonied until the evening sacrifice.
[SUP]5 [/SUP]And at the evening sacrifice I arose up from my heaviness; and having rent my garment and my mantle, I fell upon my knees, and spread out my hands unto the Lord my God,
[SUP]6 [/SUP]And said, O my God, I am ashamed and blush to lift up my face to thee, my God: for our iniquities are increased over our head, and our trespass is grown up unto the heavens.
[SUP]7 [/SUP]Since the days of our fathers have we been in a great trespass unto this day; and for our iniquities have we, our kings, and our priests, been delivered into the hand of the kings of the lands, to the sword, to captivity, and to a spoil, and to confusion of face, as it is this day.
[SUP]8 [/SUP]And now for a little space grace hath been shewed from the Lord our God, to leave us a remnant to escape, and to give us a nail in his holy place, that our God may lighten our eyes, and give us a little reviving in our bondage.
[SUP]9 [/SUP]For we were bondmen; yet our God hath not forsaken us in our bondage, but hath extended mercy unto us in the sight of the kings of Persia, to give us a reviving, to set up the house of our God, and to repair the desolations thereof, and to give us a wall in Judah and in Jerusalem.
[SUP]10 [/SUP]And now, O our God, what shall we say after this? for we have forsaken thy commandments,
[SUP]11 [/SUP]Which thou hast commanded by thy servants the prophets, saying, The land, unto which ye go to possess it, is an unclean land with the filthiness of the people of the lands, with their abominations, which have filled it from one end to another with their uncleanness.
[SUP]12 [/SUP]Now therefore give not your daughters unto their sons, neither take their daughters unto your sons, nor seek their peace or their wealth for ever: that ye may be strong, and eat the good of the land, and leave it for an inheritance to your children for ever.
[SUP]13 [/SUP]And after all that is come upon us for our evil deeds, and for our great trespass, seeing that thou our God hast punished us less than our iniquities deserve, and hast given us such deliverance as this;
[SUP]14 [/SUP]Should we again break thy commandments, and join in affinity with the people of these abominations? wouldest not thou be angry with us till thou hadst consumed us, so that there should be no remnant nor escaping?
[SUP]15 [/SUP]O Lord God of Israel, thou art righteous: for we remain yet escaped, as it is this day: behold, we are before thee in our trespasses: for we cannot stand before thee because of this.
Genesis 21:10
[SUP]10 [/SUP]Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.
Genesis 24:2-4
[SUP]2 [/SUP]And Abraham said unto his eldest servant of his house, that ruled over all that he had, Put, I pray thee, thy hand under my thigh:
[SUP]3 [/SUP]And I will make thee swear by the Lord, the God of heaven, and the God of the earth, that thou shalt not take a wife unto my son of the daughters of the Canaanites, among whom I dwell:
[SUP]4 [/SUP]But thou shalt go unto my country, and to my kindred, and take a wife unto my son Isaac.
Genesis 26:34-35
[SUP]34 [/SUP]And Esau was forty years old when he took to wife Judith the daughter of Beeri the Hittite, and Bashemath the daughter of Elon the Hittite:
[SUP]35 [/SUP]Which were a grief of mind unto Isaac and to Rebekah.
Genesis 28:1-3
1 And Isaac called Jacob, and blessed him, and charged him, and said unto him, Thou shalt not take a wife of the daughters of Canaan.
[SUP]2 [/SUP]Arise, go to Padanaram, to the house of Bethuel thy mother's father; and take thee a wife from thence of the daughers of Laban thy mother's brother.
[SUP]3 [/SUP]And God Almighty bless thee, and make thee fruitful, and multiply thee, that thou mayest be a multitude of people;
Deuteronomy 7:1-6
1 When the Lord thy God shall bring thee into the land whither thou goest to possess it, and hath cast out many nations before thee, the Hittites, and the Girgashites, and the Amorites, and the Canaanites, and the Perizzites, and the Hivites, and the Jebusites, seven nations greater and mightier than thou;
[SUP]2 [/SUP]And when the Lord thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them:
[SUP]3 [/SUP]Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.
[SUP]4 [/SUP]For they will turn away thy son from following me, that they may serve other gods: so will the anger of the Lord be kindled against you, and destroy thee suddenly.
[SUP]5 [/SUP]But thus shall ye deal with them; ye shall destroy their altars, and break down their images, and cut down their groves, and burn their graven images with fire.
[SUP]6 [/SUP]For thou art an holy people unto the Lord thy God: the Lord thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth.
Nehemiah 13:23-27
[SUP]23 [/SUP]In those days also saw I Jews that had married wives of Ashdod, of Ammon, and of Moab:
[SUP]24 [/SUP]And their children spake half in the speech of Ashdod, and could not speak in the Jews' language, but according to the language of each people.
[SUP]25 [/SUP]And I contended with them, and cursed them, and smote certain of them, and plucked off their hair, and made them swear by God, saying, Ye shall not give your daughters unto their sons, nor take their daughters unto your sons, or for yourselves.
[SUP]26 [/SUP]Did not Solomon king of Israel sin by these things? yet among many nations was there no king like him, who was beloved of his God, and God made him king over all Israel: nevertheless even him did outlandish women cause to sin.
[SUP]27 [/SUP]Shall we then hearken unto you to do all this great evil, to transgress against our God in marrying strange wives?
