Exodus 27:3-7

3And thou shalt make its pans to receive its ashes, and its shovels, and its basins, and its fleshhooks, and its firepans: all its vessels thou shalt make of brass.

4And thou shalt make for it a grate of network of brass; and upon the net shalt thou make four brasen rings in its four corners.

5And thou shalt put it under the rim of the altar beneath, that the net may be even to the midst of the altar.

6And thou shalt make staffs for the altar, staffs of shittim wood, and overlay them with brass.

7And the staffs shall be put into the rings, and the staffs shall be upon the two sides of the altar, to bear it.
