The Rods Are To Be Laid Up in the Tent of Meeting before the Testimony (Numbers 17:4).
‘And you shall lay them up in the tent of meeting before the testimony, where I meet with you.'
These were then to be ‘laid up in the Tent of meeting, before the testimony', in the place where Yahweh meets with His people. This probably meant in front of the veil behind which was the Ark of the covenant of Yahweh, ‘the testimony' indicating the presence of the covenant tablets in the Ark and their testimony to the covenant.
