Deuteronômio 7

Deuteronômio 7:1

These are the seven nations whose lands the Lord promised to give to the children of Israel when they left Egypt. We must accept the fact that, according to the apostle, all the things that happened to them in a figure were written for our instruction.… The reason that they are said to be much more numerous is that there are more vices than virtues. Therefore in the list they are counted as seven nations, to be sure, but when it is a question of destroying them they are said to be innumerable. — CONFERENCE 5.16.1-2
