'Watch' in the Bible

The Levites are to camp around the tabernacle of the testimony and watch over it, so that no wrath will fall on the Israelite community.”

But the Kohathites are not to go in to watch while the holy things are being covered, or they will die."

The Lord bless you, and keep you [protect you, sustain you, and guard you];

He may minister to his brothers at the Tent of Meeting by keeping watch, but he is not to engage in service. This is how you are to act with respect to the obligations of the descendants of Levi."

And they put him under watch because it was not made clear what should be done to him.

“Take the staff and assemble the community. You and your brother Aaron are to speak to the rock while they watch, and it will yield its water. You will bring out water for them from the rock and provide drink for the community and their livestock.”

I see them from the top of rocky cliffs,and I watch them from the hills.There is a people living alone;it does not consider itself among the nations.
