Nehemiah 2:8
2:8 and a letter for Asaph the keeper of the king’s nature preserve, so that he will give me timber for beams for the gates of the fortress adjacent to the temple and for the city wall and for the house to which I go.” So the king granted me these requests, for the good hand of my God was on me.
Nehemiah 7:3
7:3 I said to them, “The gates of Jerusalem must not be opened in the early morning, until those who are standing guard close the doors and lock them. Position residents of Jerusalem as guards, some at their guard stations and some near their homes.”
Nehemiah 13:22
13:22 Then I directed the Levites to purify themselves and come and guard the gates in order to keep the Sabbath day holy. For this please remember me, O my God, and have pity on me in keeping with your great love.
