'Twenty' in the Bible

A man from Baal Shalishah came, and brought the man of God bread of the first fruits, twenty loaves of barley, and fresh ears of grain in his sack. He said, "Give to the people, that they may eat."

In the two and fiftieth year of Azariah king of Judah Pekah the son of Remaliah began to reign over Israel in Samaria, [and reigned] twenty years.

Twenty years old was Ahaz when he began to reign; and he reigned sixteen years in Jerusalem: and he didn't do that which was right in the eyes of Yahweh his God, like David his father.
