I said to them, "Do not open the gates of Jerusalem until the sun is hot. While they are standing guard let them shut and fasten the doors. And appoint guards from the inhabitants of Jerusalem, one at his post and another opposite his house."

Mattaniah, Bakbukiah, Obadiah, Meshullam, Talmon, and Akkub were gatekeepers standing guard at the storerooms of the gates.

and over the Gate of Ephraim, at the Old Gate, at the Fish Gate, the Tower of Hananel and the Tower of the Hundred, and [to] the Sheep Gate. And they [stopped and] stood at the Gate of the Guard.

And then I told two Levites that they must purify themselves and come to guard the gates in order to consecrate the day of the Sabbath. Remember this also, my God, and take pity on me according to the greatness of your loyal love.
