5. Mose 7:24

As the Israelites were warned against idolatry in Deu 6:14, so here are they exhorted to beware of the false tolerance of sparing the Canaanites and enduring their idolatry. - Deu 7:1, Deu 7:5. When the Lord drove out the tribes of Canaan before the Israelites, and gave them up to them and smote them, they were to put them under the ban (see at Lev 27:28), to make no treaty with them, and to contract no marriage with them. נשׁל, to draw out, to cast away, e.g., the sandals (Exo 3:5); here and Deu 7:22 it signifies to draw out, or drive out a nation from its country and possessions: it occurs in this sense in the Piel in Kg2 16:6. On the Canaanitish tribes, see at Gen 10:15. and Deu 15:20-21. There are seven of them mentioned here, as in Jos 3:10 and Jos 24:11; on the other hand, there are only six in Deu 20:17, as in Exo 3:8, Exo 3:17; Exo 23:23, and Exo 33:2, the Girgashites being omitted. The prohibition against making a covenant, as in Exo 23:32 and Exo 34:12, and that against marrying, as in Exo 34:16, where the danger of the Israelites being drawn away to idolatry is mentioned as a still further reason for these commands. יסיר כּי, "for he (the Canaanite) will cause thy son to turn away from behind me," i.e., tempt him away from following me, "to serve other gods." Moses says "from following me," because he is speaking in the name of Jehovah. The consequences of idolatry, as in Deu 6:15; Deu 4:26, etc.

Moses in this chapter exhorts Israel, I. In general, to keep God's commandments (Deu 7:11, Deu 7:12). II. In particular, and in order to that, to keep themselves pure from all communion with idolaters. 1. They must utterly destroy the seven devoted nations, and not spare them, or make leagues with them (Deu 7:1, Deu 7:2, Deu 7:16, Deu 7:24). 2. They must by no means marry with the remainders of them (Deu 7:3, Deu 7:4). 3. They must deface and consume their altars and images, and not so much as take the silver and gold of them to their own use (Deu 7:5, Deu 7:25, Deu 7:26). To enforce this charge, he shows that they were bound to do so, (1.) In duty. Considering [1.] Their election to God (Deu 7:6). [2.] The reason of that election (Deu 7:7, Deu 7:8). [3.] The terms they stood upon with God (Deu 7:9, Deu 7:10). (2.) In interest. It is here promised, [1.] In general, that, if they would serve God, he would bless and prosper them (Deu 7:12-15). [2.] In particular, that if they would drive out the nations, that they might not be a temptation to them, God would drive them out, that they should not be any vexation to them (Deu 7:17, etc.).

7:24 erase their names: An individual’s name represented that person’s existence as it would be carried into the future through generations of descendants. By destroying an entire nation, God cut off its line of descent and thus also its future. The Canaanites who suffered God’s war against them lost all their descendants and thus their existence and identity.
