'Lowest' in the Bible

The lowest chamber was 7½ feet wide, the middle was nine feet wide, and the third was 10½ feet wide. He also provided offset ledges for the temple all around the outside so that nothing would be inserted into the temple walls.

The door for the lowest side chamber was on the right side of the temple. They went up a stairway to the middle chamber, and from the middle to the third.

And he made an house of high places, and made priests of the lowest of the people, which were not of the sons of Levi.

After this thing Jeroboam returned not from his evil way, but made again of the lowest of the people priests of the high places: whosoever would, he consecrated him, and he became one of the priests of the high places.
