1 Kings 7:34

And king Solomon took the furniture which [Chiram] made for the house of the Lord, the golden altar, and the golden table of shewbread.

The four side pieces were at the four corners of each base; its shoulders [were formed] of the base.

And there were four undersetters to the four corners of one base: and the undersetters were of the very base itself.

There were four supports at the four corners of each base. Its supports were of the base itself.
