Exodus 38:5-7

Holman Christian Standard Bible

⁵ At the four corners of the bronze grate he cast four rings as holders for the poles. ⁶ Also, he made the poles of acacia wood and overlaid them with bronze. ⁷ Then he inserted the poles into the rings on the sides of the altar in order to carry it with them. He constructed the altar with boards so that it was hollow.
