Exodus 37:25-28

²⁵And he made the incense altar of shittim wood: the length of it was a cubit, and the breadth of it a cubit; it was foursquare; and two cubits was the height of it; the horns thereof were of the same. ²⁶And he overlaid it with pure gold, both the top of it, and the sides thereof round about, and the horns of it: also he made unto it a crown of gold round about. ²⁷And he made two rings of gold for it under the crown thereof, by the two corners of it, upon the two sides thereof, to be places for the staves to bear it withal. ²⁸And he made the staves of shittim wood, and overlaid them with gold.
