Exodus 38:1-2

Amplified Bible

The Tabernacle Completed

38 Then Bezalel made the altar of burnt offering of acacia wood; its top was square, five cubits long and five cubits wide, and three cubits high. ² And he made its horns (horn-shaped projections) on the four corners of it; the horns were of one piece with it, and he overlaid it with bronze.
