Joshua 24:22-25

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

²³And now put away the strange gods which are in the midst of you, and incline your heart unto the Lord the God of Israel.

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

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