'Keep Watch' in the Bible

And keep watch over your heart with all care; so you will have life.

In your walking, it will be your guide; when you are sleeping, it will keep watch over you; when you are awake, it will have talk with you.

Happy [is the] person who listens to me, [in order] to keep watch at my doors day by day, [in order] to guard the frames of my entrances.

In every place, the eyes of Yahweh keep watch over the evil and the good.

The eyes of Yahweh keep watch over knowledge, but he will overthrow the words of the faithless.
