Joshua 24:1-2, 11-28

Then Joshua gathered all the tribes of Israel to Shechem, and summoned the
elders, the heads, the judges, and the officers of Israel; and they
presented themselves before God.  And Joshua said to all the people, "Thus
says the LORD, the God of Israel: Long ago your ancestors — Terah and his
sons Abraham and Nahor — lived beyond the Euphrates and served other gods.

When you went over the Jordan and came to Jericho, the citizens of Jericho
fought against you, and also the Amorites, the Perizzites, the Canaanites,
the Hittites, the Girgashites, the Hivites, and the Jebusites; and I
handed them over to you.  I sent the hornet ahead of you, which drove out
before you the two kings of the Amorites; it was not by your sword or by
your bow.  I gave you a land on which you had not labored, and towns that
you had not built, and you live in them; you eat the fruit of vineyards
and oliveyards that you did not plant.

"Now therefore revere the LORD, and serve him in sincerity and in
faithfulness; put away the gods that your ancestors served beyond the
River and in Egypt, and serve the LORD.  Now if you are unwilling to serve
the LORD, choose this day whom you will serve, whether the gods your
ancestors served in the region beyond the River or the gods of the
Amorites in whose land you are living; but as for me and my household, we
will serve the LORD."

Then the people answered, "Far be it from us that we should forsake the
LORD to serve other gods; for it is the LORD our God who brought us and
our ancestors up from the land of Egypt, out of the house of slavery, and
who did those great signs in our sight.  He protected us along all the way
that we went, and among all the peoples through whom we passed; and the
LORD drove out before us all the peoples, the Amorites who lived in the
land.  Therefore we also will serve the LORD, for he is our God."

But Joshua said to the people, "You cannot serve the LORD, for he is a
holy God.  He is a jealous God; he will not forgive your transgressions or
your sins.  If you forsake the LORD and serve foreign gods, then he will
turn and do you harm, and consume you, after having done you good."  And
the people said to Joshua, "No, we will serve the LORD!"  Then Joshua said
to the people, "You are witnesses against yourselves that you have chosen
the LORD, to serve him." And they said, "We are witnesses."  He said,
"Then put away the foreign gods that are among you, and incline your
hearts to the LORD, the God of Israel."  The people said to Joshua, "The
LORD our God we will serve, and him we will obey."  So Joshua made a
covenant with the people that day, and made statutes and ordinances for
them at Shechem.  Joshua wrote these words in the book of the law of God;
and he took a large stone, and set it up there under the oak in the
sanctuary of the LORD.  Joshua said to all the people, "See, this stone
shall be a witness against us; for it has heard all the words of the LORD
that he spoke to us; therefore it shall be a witness against you, if you
deal falsely with your God."  So Joshua sent the people away to their
inheritances.
