Nehemiah 4:6-9

So we built the wall, and the entire wall was joined together up to half its height, for the people had a mind to work. Now it happened, when Sanballat, Tobiah, the Arabs, the Ammonites, and the Ashdodites heard that the walls of Jerusalem were being restored and the gaps were beginning to be closed, that they became very angry, and all of them conspired together to come and attack Jerusalem and create confusion. Nevertheless we made our prayer to our God, and because of them we set a watch against them day and night.
