Joshua 24:19-23

Then Joshua said to the people, “You will not be able to serve the Lord, for He is a holy God. He is a jealous God; He will not forgive your wrongdoing or your sins.

If you abandon the Lord and serve foreign gods, then He will turn and do you harm and destroy you after He has done good to you.”

And the people said to Joshua, “No, but we will serve the Lord.”

So Joshua said to the people, “You are witnesses against yourselves that you have chosen for yourselves the Lord, to serve Him.” And they said, “We are witnesses.”

“Now then, do away with the foreign gods which are in your midst, and incline your hearts to the Lord, the God of Israel.”
