Psalm 78 (KJV)

6 That the generation to come might know them, even the children which should be born; who should arise and declare them to their children:
7 That they might set their hope in God, and not forget the works of God, but keep his commandments:
8 And might not be as their fathers, a stubborn and rebellious generation; a generation that set not their heart aright, and whose spirit was not stedfast (unwavering or determined in purpose, loyalty) with God.

38 But he, being full of compassion, forgave their iniquity (wickedness), and destroyed them not: yea, many a time turned he his anger away, and did not stir up all his wrath.
39 For he remembered that they were but flesh; a wind that passeth away, and cometh not again.
40 How oft did they provoke him in the wilderness, and grieve him in the desert!
41 Yea, they turned back and tempted God, and limited the Holy One of Israel.
42 They remembered not his hand, nor the day when he delivered them from the enemy.

49 He cast upon them the fierceness of his anger, wrath, and indignation (displeasure or annoyance), and trouble, by sending evil angels among them.

72 So he fed them according to the integrity (purity, goodness, honorableness) of his heart; and guided them by the skilfulness of his hands.
