'Bit' in the Bible

The Lord sent fiery serpents among the people and they bit the people, so that many people of Israel died.

And Moses made a bronze serpent and set it on the standard; and it came about, that if a serpent bit any man, when he looked to the bronze serpent, he lived.

Do not be as the horse or as the mule which have no understanding,Whose trappings include bit and bridle to hold them in check,Otherwise they will not come near to you.
