Exodus 34:12-16

DouayRheims(i) 12 Beware thou never join in friendship with the inhabitants of that land, which may be thy ruin: 13 But destroy their altars, break their statues and cut down their groves: 14 Adore not any strange god. The Lord his name is jealous, he is a jealous God. 15 Make no covenant with the men of those countries; lest, when they have committed fornication with their gods, and have adored their idols, some one call thee to eat of the things sacrificed. 16 Neither shalt thou take of their daughters a wife for thy son, lest after they themselves have committed fornication, they make thy sons also to commit fornication with their gods.
