Exodus 38:5-7

The Voice

⁵ He cast four bronze rings and attached them at the four corners of the bronze grating in order to hold the poles. ⁶ He made poles out of acacia wood and overlaid them with bronze. ⁷ He then slid the poles through the rings on both sides of the altar so that it could be carried. He made the altar out of wooden planks and made it hollow so that it would be easier to move.
