Exodus 38:5-7

Darby Translation

⁵ And he cast four rings for the four corners of the grating of copper, as receptacles for the staves.

⁶ And he made the staves of acacia-wood, and overlaid them with copper.

⁷ And he put the staves into the rings on the sides of the altar, with which to carry it. Hollow with boards did he make it.
