‘ So David and all the house of Israel brought up the ark of YHWH with shouting, and with the sound of the trumpet.'
So this was the way in which David and all the house of Israel brought up the Ark of YHWH. And they did it with shouting and the blaring of ram's horns. It was to be seen as the procession of a King even greater than David. From now on YHWH would reign in Zion.
