'Sun rising' in the Bible

And the Nethinims were dwelling in Ophel even to the front of the gate of waters to the sunrising, and the tower coming forth.

After him held fast Zadok son of Immer, before his house. And after him held fast Shemaiah son of Shecaniah, watching the gate of the sunrising.

And at the gate of the fountain, and before them, they went up upon the steps of the city of David in the going up to the wall from above to the house: of David, and even to the gate of waters of the sunrising.
