1 Kings 6:20

1Ki 6:20 And the oracle in the forepart [was] twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof: and he overlaid it with pure gold; and [so] covered the altar [which was of] cedar.

Ver. 20. Twenty cubits in length. ] So that it was every way square.

Overlaid it with pure gold. ] Heb., With gold shut up; so called, haply, because men used to hoard up the best gold, and keep it close prisoner, as it were.

And so covered the altar. ] Which being wood within, and gold without, shadowed out Christ - the true altar Heb 13:10 - in his twofold nature, human and divine.
