Exodus 27:6-8

Young's Literal Translation

⁶ `And thou hast made staves for the altar, staves of shittim wood, and hast overlaid them [with] brass.

⁷ And the staves have been brought into the rings, and the staves have been on the two sides of the altar in bearing it.

⁸ Hollow with boards thou dost make it, as it hath been shewed thee in the mount, so do they make [it].
