2 Chronicles 15:12-14 MSG

12 Then they bound themselves in a covenant to seek God, the God of their fathers, wholeheartedly, holding nothing back.
13 And they agreed that anyone who refused to seek God, the God of Israel, should be killed, no matter who it was, young or old, man or woman.
14 They shouted out their promise to God, a joyful sound accompanied with blasts from trumpets and rams' horns.
