Exodus 34:16 And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods.
Deuteronomy 7:3 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.
Ezra 9:1-
3 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. ... 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.
Ezra 9:12-
14 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. ... 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?
Ezra 10:10-
12 And Ezra the priest stood up, and said unto them, Ye have transgressed, and have
taken strange wives, to increase the trespass of Israel. ... Then all the congregation answered and said with a loud voice,
As thou hast said,
so must we do.
