Deu 7:6 For you are a holy people belonging to the LORD your God. The LORD your God has chosen you to be his own possession out of all the peoples on the face of the earth.
The basis for the command to destroy the Canaanites lay in God’s election of Israel. The word translated chosen means “to be chosen for a task or a vocation.” God had selected Israel as His means of sanctifying the earth. Thus, they were holy (set apart for God’s special use) and were His treasured possession. Since the Canaanites were polluting the earth, and since they might endanger Israel’s complete subordination to the will of the Lord, they either had to repent or be eliminated. And as stated, for 400 years they had refused to repent.
