Strong's H4350 מְכוֹנָה (mekonah)

And he made ten bases of brass; four cubits was the length of one base, and four cubits the breadth thereof, and three cubits the height of it.

And the work of the bases was on this manner: they had borders, and the borders were between the ledges:

And every base had four brasen wheels, and plates of brass: and the four corners thereof had undersetters: under the laver were undersetters molten, at the side of every addition.

And under the borders were four wheels; and the axletrees of the wheels were joined to the base: and the height of a wheel was a cubit and half a cubit.

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

And in the top of the base was there a round compass of half a cubit high: and on the top of the base the ledges thereof and the borders thereof were of the same.

After this manner he made the ten bases: all of them had one casting, one measure, and one size.

Then made he ten lavers of brass: one laver contained forty baths: and every laver was four cubits: and upon every one of the ten bases one laver.

And he put five bases on the right side of the house, and five on the left side of the house: and he set the sea on the right side of the house eastward over against the south.

And the ten bases, and ten lavers on the bases;

And king Ahaz cut off the borders of the bases, and removed the laver from off them; and took down the sea from off the brasen oxen that were under it, and put it upon the pavement of stones.

And the pillars of brass that were in the house of the LORD, and the bases, and the brasen sea that was in the house of the LORD, did the Chaldees break in pieces, and carried the brass of them to Babylon.

The two pillars, one sea, and the bases which Solomon had made for the house of the LORD; the brass of all these vessels was without weight.

He made also bases, and lavers made he upon the bases;

And they set the altar upon his bases; for fear was upon them because of the people of those countries: and they offered burnt offerings thereon unto the LORD, even burnt offerings morning and evening.

For thus saith the LORD of hosts concerning the pillars, and concerning the sea, and concerning the bases, and concerning the residue of the vessels that remain in this city.

Also the pillars of brass that were in the house of the LORD, and the bases, and the brasen sea that was in the house of the LORD, the Chaldeans brake, and carried all the brass of them to Babylon.

The two pillars, one sea, and twelve brasen bulls that were under the bases, which king Solomon had made in the house of the LORD: the brass of all these vessels was without weight.
