Joshua 6:8

And it came to pass, when Joshua had spoken to the people
Both armed and unarmed; had finished the orders and directions he gave them before mentioned:

that the seven priests bearing the seven trumpets of rams' horns
passed on before the Lord;
in his sight, and by his direction, and at his command given by Joshua, and before the ark, the symbol of his presence:

and blew with the trumpets;
a short blast as they went along; this they did on each of the six days:

and the ark of the covenant of the Lord followed them;
being borne by priests, ( Joshua 6:6 ) .
