Psalms 78:7,8

That they might set their hope in God That by the consideration of God's gracious promises, and his wonderful works wrought for his people, they might be encouraged to adhere to him, and trust in him alone. And might not be as their fathers Who, though they were the seed of Abraham, the father of the faithful, taken into covenant with God, and, it appears, the only professing people he had then in the world, yet were stubborn and rebellious, walking contrary to God, and in direct opposition to his will. A generation that set not their heart aright Who, when they outwardly and seemingly complied with the forms of worship which God had prescribed, yet did not direct or prepare their hearts to the obedience and service of God; and whose spirit was not steadfast with God Who quickly discovered their hypocrisy by their apostacy from God, and from the religion which they professed, falling off from him even to the worship of idols, presently after they came out of Egypt.
