“Build an altar of acacia wood, three cubits high; it is to be square, five cubits long and five cubits wide. ² Make a horn at each of the four corners, so that the horns and the altar are of one piece, and overlay the altar with bronze.

⁸ Make the altar hollow, out of boards. It is to be made just as you were shown on the mountain. 

⁹ “Make a courtyard for the tabernacle. The south side shall be a hundred cubits long and is to have curtains of finely twisted linen, ¹⁰ with twenty posts and twenty bronze bases and with silver hooks and bands on the posts.

¹⁹ All the other articles used in the service of the tabernacle, whatever their function, including all the tent pegs for it and those for the courtyard, are to be of bronze.
