'Bits' in the Bible

Therefore Jacob’s iniquity will be purged in this way,and the result of the removal of his sin will be this:when he makes all the altar stoneslike crushed bits of chalk,no Asherah poles or incense altars will remain standing.

For this thing is from Israel—a craftsman made it, and it is not God.The calf of Samaria will be smashed to bits!

Now when we put bits into the mouths of horses to make them obey us, we also guide the whole animal.
