Psalms 78:7 - Exposition

That they might set their hope in God. Instruction in God's Law, and in his treatment of their forefathers, would naturally tend to make the Israelites "set their hope in God," who in the past had done so much for them. And not forget the works of God. They could not well forget, it' they were perpetually reminded of them. But keep his commandments. If they bore God's works— i.e. his many mercies—in mind, they would be the more disposed to obedience.
