'Base' in the Bible

So I will let the wall, which you were covering with whitewash, be broken down; I will have it levelled to the earth so that its base is uncovered: it will come down, and destruction will come on you with it; and it will be clear to you that I am the Lord.

And there was a wall on the outside of the house all round, and in the man's hand there was a measuring rod six cubits long by a cubit and a hand's measure: so he took the measure of the building from side to side, one rod; and from base to top, one rod.

The altar was made of wood, and was three cubits high and two cubits long; it had angles, and its base and sides were of wood; and he said to me, This is the table which is before the Lord.

And these are the measures of the altar in cubits: (the cubit being a cubit and a hand's measure;) its hollow base is a cubit high and a cubit wide, and it has an overhanging edge as wide as a hand-stretch all round it:

And from the base on the earth level to the lower shelf, the altar is two cubits high and a cubit wide; and from the smaller shelf to the greater shelf it is four cubits high and a cubit wide.

And the shelf is fourteen cubits long and fourteen cubits wide, on its four sides; the edge round it is half a cubit; the base of it is a cubit all round, and its steps are facing the east.
