'Bits' in the Bible

Is not my word like fire? says the Lord; and like a hammer, smashing the rock to bits?

So Ebed-melech took the men with him and went into the house of the king, to the place where the clothing was kept, and got from there old clothing and bits of old cloth, and let them down by cords into the water-hole where Jeremiah was.

And Ebed-melech the Ethiopian said to Jeremiah, Put these bits of old cloth under your arms under the cords. And Jeremiah did so.
