me.kho.nah denotes a supporting stand or base, especially for basins and an altar.

The term denotes a constructed supporting stand or base: the bronze structures beneath basins in the house and the bases on which an altar was set. The same designation remains in view when these bronze items are altered, broken up, or listed among temple vessels.

1. Supporting stand or base · dominant

   In 1 Kings 7:27, the plural form names ten bronze structures with stated dimensions; 1 Kings 7:38 places a basin on each one. The singular form in 1 Kings 7:30 is associated with wheels, axles, and supports, while Ezra 3:3 uses the plural construct form for the bases on which the altar was set. Later notices retain the same concrete object among bronze temple items, as in 2 Kings 25:13.

In the Anselm Project Bible: The APB commonly presents the item as “stands” in the bronze-basin descriptions, but also uses “bases” for the altar setting and a vessel list. These renderings reflect the verses' descriptions of supporting structures rather than separate lexical senses.
