'Gaps' in the Bible

When Sanballat, Tobiah, and the Arabs, Ammonites, and Ashdodites heard that the repair to the walls of Jerusalem was progressing and that the gaps were being closed, they became furious.

You did not go up to the gaps or restore the wall around the house of Israel so that it might stand in battle on the day of the Lord.

In that dayI will restore the fallen booth of David:I will repair its gaps,restore its ruins,and rebuild it as in the days of old,
