[147] Now between this candlestick and the table, which, as we said, were within the sanctuary, was the altar of incense, made of wood indeed, but of the same wood of which the foregoing vessels were made, such as was not liable to corruption; it was entirely crusted over with a golden plate. Its breadth on each side was a cubit, but the altitude double. Upon it was a grate of gold, that was extant above the altar, which had a golden crown encompassing it round about, whereto belonged rings and bars, by which the priests carried it when they journeyed. Before this tabernacle there was reared a brazen altar, but it was within made of wood, five cubits by measure on each side, but its height was but three, in like manner adorned with brass plates as bright as gold. It had also a brazen hearth of network; for the ground underneath received the fire from the hearth, because it had no basis to receive it. Hard by this altar lay the basins, and the vials, and the censers, and the caldrons, made of gold; but the other vessels, made for the use of the sacrifices, were all of brass. And such was the construction of the tabernacle; and these were the vessels thereto belonging.
