Exodus 27:3-7

3You shall make its pails for removing its ashes, and its shovels and its basins and its forks and its firepans; you shall make all its utensils of bronze.

4You shall make for it a grating of network of bronze, and on the net you shall make four bronze rings 1at its four corners.

5You shall put it beneath, under the ledge of the altar, so that the net will reach halfway up the altar.

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

7Its poles shall be inserted into the rings, so that the poles shall be on the two sides of the altar 2when it is carried.
