Joshua 6:9

And let the men of war proceed before, and the priests bringing up the rear behind the ark of the covenant of the Lord [proceed] sounding the trumpets.

And the armed men went before the priests that blew with the trumpets, and the rereward came after the ark, the priests going on, and blowing with the trumpets.

The armed men went before the priests who blew the trumpets, and the ark went after them. The trumpets sounded as they went.
