Joshua 6:1-3

Now Jericho was straitly shut up because of the children of Israel: none went out, and none came in.

And the LORD said unto Joshua, See, I have given into thine hand Jericho, and the king thereof, and the mighty men of valour.

And ye shall compass the city, all ye men of war, and go round about the city once. Thus shalt thou do six days.
