The Lord hath expressly commanded (Deuteronomy 7:1-4.) that there should be no intermarriages between Israel and the nations around. Chiefly, no doubt, with an eye to Christ. God's people were a nation of priests, an holy seed, a peculiar people, a royal priesthood. Therefore this mingling with the heathens was a direct outrage to the divine law. Alas! what are we not capable of doing, when the Lord withholds his grace! And, Reader! have you never remarked in your own instance, how sometimes this is done to teach us what we are, and to cause us to look back again to the hole from whence we were digged. Isaiah 51:1.

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.
2 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.
