Exodus 37:25
And 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. And 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.
The verse records God's instruction to Moses for making the incense altar as part of the tabernacle. That making belonged to the skillful work appointed to adorn the sanctuary. The work was carried out by skillful men, who made the altar and the vessels of solid gold. Alongside them, women wrought the embroidery in silver and gold.
