And they were for to prove Israel by them, to know whether they would hearken unto the commandments of the LORD, which he commanded their fathers by the hand of Moses.
And he cried unto the LORD; and the LORD shewed him a tree, and he cast it into the waters, and the waters were made sweet. There he made for them a statute and an ordinance, and there he proved them;
And of Levi he said, Thy Thummim and thy Urim are with thy godly one, Whom thou didst prove at Massah, With whom thou didst strive at the waters of Meribah;
And thou shalt remember all the way which the LORD thy God hath led thee these forty years in the wilderness, that he might humble thee, to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no.
