'Lookout' in the Bible

When Judah came to the lookout of the wilderness, they looked toward the multitude, and behold, they were corpses lying on the ground, and no one had escaped.

For thus the Lord says to me,“Go, station the lookout, let him report what he sees.

Then the lookout called,“O Lord, I stand continually by day on the watchtower,And I am stationed every night at my guard post.

do not merely look out for your own personal interests, but also for the interests of others.
