Exodus 27:3-7

3You are to make pots for it to take away ashes, along with shovels, basins, forks and fire pans—make all the utensils of bronze.

4Also make a bronze grating net for it, and on the net you are to make four bronze rings on the four corners.

5You are to place it under the ledge around the altar beneath, so that the net may reach halfway up the altar.

6Make poles for the altar, poles of acacia wood, and overlay them with bronze.

7Its poles are to be put into the rings, on the two sides of the altar, for carrying it.
