'Gap' in the Bible

The people had compassion on Benjamin, because the Lord had made this gap in the tribes of Israel.

This is what prompted him to rebel against the king: Solomon built a terrace and he closed up a gap in the wall of the city of his father David.

When Sanballat, Tobiah, Geshem the Arab, and the rest of our enemies heard that I had rebuilt the wall and that no gap was left in it—though at that time I had not installed the doors in the gates—

And I sought for a man among them, that should make up the hedge, and stand in the gap before me for the land, that I should not destroy it: but I found none.
