Joshua 24:22-25

²²And Joshua said unto the people, Ye are witnesses against yourselves that ye have chosen you the Lord, to serve him. And they said, We are witnesses.

²³Now therefore put away, said he, the strange gods which are among you, and incline your heart unto the Lord God of Israel.

²⁴And the people said unto Joshua, The Lord our God will we serve, and his voice will we obey.

²⁵So Joshua made a covenant with the people that day, and set them a statute and an ordinance in Shechem.
