Joshua 3:5-7

5 Yehoshua said to the people, Sanctify yourselves; for tomorrow the LORD will do wonders among you.
6 Yehoshua spoke to the Kohanim, saying, Take up the ark of the covenant, and pass over before the people. They took up the ark of the covenant, and went before the people.
7 The LORD said to Yehoshua, This day will I begin to magnify you in the sight of all Yisra'el, that they may know that, as I was with Moshe, so I will be with you.
