'Watched' in the Bible

so that men shall say, "Most certainly there is a reward for the righteous. Most certainly there is a God who judges the earth." For the Chief Musician. To the tune of "Do Not Destroy." A poem by David, when Saul sent, and they watched the house to kill him.

{To the chief Musician, Altaschith, Michtam of David; when Saul sent, and they watched the house to kill him.} Deliver me from mine enemies, O my God: defend me from them that rise up against me.

I have watched, and I am As a bird alone on the roof.
