In Context

6 That the generation to come might know them, even the children which should be born; who should arise and tell 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 with God.

9 The children of Ephraim, being armed and carrying bows, turned back in the day of battle.

10 They kept not the covenant of God, and refused to walk in his law;

11 And they forgat his doings, and his wondrous works that he had shewed them.
