Joshua 6:8

‘And so it was that when Joshua had spoken to the people, the seven priests bearing the seven trumpets of rams' horns passed on before YHWH, and blew with the trumpets, and the Ark of the covenant of YHWH followed them.'

Joshua having given his instructions to the people, whether directly or through the priests, the seven priests with the rams' horns ‘passed on before YHWH'. Here ‘the Ark of YHWH' is replaced by ‘YHWH' Himself, for YHWH is seen as sitting on His moveable battle throne, borne by the priests, ready to reveal His power against the enemy (compare Ezekiel 1:16; Ezekiel 1:19 where the heavenly equivalent of the Ark is seen as having heavenly wheels). The seven trumpets of rams' horns meanwhile sounded out the power of YHWH. In the description of the Ark both the covenant and YHWH Himself are now given prominence. It was because they were His covenant People that Jericho, and the whole land, ha been given to them.
