'Rear guard' in the Bible

And, the armed host, went on before the priests who blew with the horns, - and, the rear-guard, came after the ark, going on and blowing with the horns.

and, the seven priests who bare the seven rams' horns before the ark of Yahweh, went on and on, and blew with the horns, - with, the armed host going on before them, and, the rear-guard, coming after the ark of Yahweh, going on and blowing with the horns.

For, not in haste, shall ye come forth, Nor, by flight, shall ye journey, - For, your van-guard, is Yahweh, And, your rear-guard, the God of Israel.
