1 Kings 9:4

4 Also if thou goest before me, as thy father went, in simpleness of heart, and in equity, and doest all things which I have commanded to thee, and keepest my dooms, and my lawful things, (And if thou goest before me, as thy father went, with integrity, and uprightness, and doest all the things which I have commanded to thee, and obeyest my judgements, and my laws,)
