Commentaries:
Israel never really trusted God. Breaking the sixth commandment was merely the next step in the process of sin. Having committed the sin of doubt, they went on to commit the sin of war. God was determined to work out His purpose to give the land to Abraham and his descendants. Israel chose to be a war-making nation, but because God's purpose must stand regardless of what men do, he continued to back Israel in their conquest of the land and ordered wars.
