'Bases' in the Bible

This is what the Lord has said: If the heavens on high may be measured, and the bases of the earth searched out, then I will give up the seed of Israel, because of all they have done, says the Lord.

And the brass pillars which were in the house of the Lord, and the wheeled bases and the great brass water-vessel in the house of the Lord, were broken up by the Chaldaeans, who took all the brass away to Babylon.

The two pillars, the great water-vessel, and the twelve brass oxen which were under it, and the ten wheeled bases, which King Solomon had made for the house of the Lord: the brass of all these vessels was without weight.
