Joshua 22:5

But take diligent heed, watch with the greatest carefulness, to do the commandment and the Law, both that of the general Moral Law and that of the special precepts given to Israel, which Moses, the servant of the Lord, charged you, to love the Lord, your God, and to walk in all His ways, and to keep His commandments, and to cleave unto Him, and to serve Him with all your heart and with all your soul. This parting admonition of Joshua shows his understanding of the human heart with its changeableness, deceitfulness, and wickedness. Cf Deuteronomy 4:2; Deuteronomy 6:5; Deuteronomy 8:6.
