Judg.3:
[1] Now these are the nations which the LORD left, to prove Israel by them, even as many of Israel as had not known all the wars of Canaan;[2] Only that the generations of the children of Israel might know, to teach them war, at the least such as before knew nothing thereof;[3] Namely, five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baal-hermon unto the entering in of Hamath.[7] And the children of Israel did evil in the sight of the LORD, and forgat the LORD their God, and served Baalim and the groves.
[8] Therefore the anger of the LORD was hot against Israel
, and he sold them into the hand of Chushan-rishathaim king of Mesopotamia: and the children of Israel served Chushan-rishathaim eight years.[31] And Rehoboam slept with his fathers, and was buried with his fathers in the city of David. And his mother's name was Naamah an Ammonitess. And Abijam his son reigned in his stead.
2Chr.12[13] So king Rehoboam strengthened himself in Jerusalem, and reigned: for Rehoboam was one and forty years old when he began to reign, and he reigned seventeen years in Jerusalem, the city which the LORD had chosen out of all the tribes of Israel, to put his name there. And his mother's name was Naamah an Ammonitess. Ruth.4[5] Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.[10] Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.
Ezr 9:2For 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.
[12] 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.
Ezra.10[2] And Shechaniah the son of Jehiel, one of the sons of Elam, answered and said unto Ezra, We have trespassed against our God, and have taken strange wives of the people of the land: yet now there is hope in Israel concerning this thing.[10] And Ezra the priest stood up, and said unto them, Ye have transgressed, and have taken strange wives, to increase the trespass of Israel.
[11] Now therefore make confession unto the LORD God of your fathers, and do his pleasure: and separate yourselves from the people of the land, and from the strange wives.
[12] Then all the congregation answered and said with a loud voice, As thou hast said, so must we do.
[13] But the people are many, and it is a time of much rain, and we are not able to stand without, neither is this a work of one day or two: for we are many that have transgressed in this thing.
[14] Let now our rulers of all the congregation stand, and let all them which have taken strange wives in our cities come at appointed times, and with them the elders of every city, and the judges thereof, until the fierce wrath of our God for this matter be turned from us.
[15] Only Jonathan the son of Asahel and Jahaziah the son of Tikvah were employed about this matter: and Meshullam and Shabbethai the Levite helped them.
[16] And the children of the captivity did so. And Ezra the priest, with certain chief of the fathers, after the house of their fathers, and all of them by their names, were separated, and sat down in the first day of the tenth month to examine the matter.
[17] And they made an end with all the men that had taken strange wives by the first day of the first month.
[18] And among the sons of the priests there were found that had taken strange wives: namely, of the sons of Jeshua the son of Jozadak, and his brethren; Maaseiah, and Eliezer, and Jarib, and Gedaliah.
[19] And they gave their hands that they would put away their wives; and being guilty, they offered a ram of the flock for their trespass.
[44] All these had taken strange wives: and some of them had wives by whom they had children.
[23] In those days also saw I Jews that had married wives of Ashdod, of Ammon, and of Moab:
[24] 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.
[25] 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.
[26] 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.(27 Shall we then hearken unto you to do all this great evil, to transgress against our God in marrying strange wives?[28] And one of the sons of Joiada, the son of Eliashib the high priest, was son in law to Sanballat the Horonite: therefore I chased him from me.
Pss.106[34] They did not destroy the nations, concerning whom the LORD commanded them:[35] But were mingled among the heathen, and learned their works.[36] And they served their idols: which were a snare unto them.[37] Yea, they sacrificed their sons and their daughters unto devils,[38] And shed innocent blood, even the blood of their sons and of their daughters, whom they sacrificed unto the idols of Canaan: and the land was polluted with blood.
