Exodus 38:5 ASV

³  And he made all the vessels of the altar, the pots, and the shovels, and the basins, the flesh-hooks, and the firepans: all the vessels thereof made he of brass.

⁴  And he made for the altar a grating of network of brass, under the ledge round it beneath, reaching halfway up.

⁵  And he cast four rings for the four ends of the grating of brass, to be places for the staves.

⁶  And he made the staves of acacia wood, and overlaid them with brass.

⁷  And he put the staves into the rings on the sides of the altar, wherewith to bear it; he made it hollow with planks.
