'Watches' in the Bible

I said to them, "Don't let the gates of Jerusalem be opened until the sun is hot; and while they stand guard, let them shut the doors, and you bar them: and appoint watches of the inhabitants of Jerusalem, everyone in his watch, with everyone near his house."

The wicked watches the righteous, and seeks to kill him.

when I remember you on my bed, and think about you in the night watches.

My eyes stay open through the night watches, that I might meditate on your word.

Unless Yahweh builds the house, they labor in vain who build it. Unless Yahweh watches over the city, the watchman guards it in vain.

Arise, cry out in the night, at the beginning of the watches; Pour out your heart like water before the face of the Lord: Lift up your hands toward him for the life of your young children, that faint for hunger at the head of every street.

A prophet watches over Ephraim with my God. A fowler's snare is on all of his paths, and hostility in the house of his God.

"Behold, I come like a thief. Blessed is he who watches, and keeps his clothes, so that he doesn't walk naked, and they see his shame."
