Exodus 27:3-7

3You are to make its pots for the ashes, its shovels, its tossing bowls, its meat hooks, and its fire pans – you are to make all its utensils of bronze.

4You are to make a grating for it, a network of bronze, and you are to make on the network four bronze rings on its four corners.

5You are to put it under the ledge of the altar below, so that the network will come halfway up the altar.

6You are to make poles for the altar, poles of acacia wood, and you are to overlay them with bronze.

7The poles are to be put into the rings so that the poles will be on two sides of the altar when carrying it.
