'Seek' in the Bible

David was afraid because Saul had come out to seek his life while David was in the wilderness of Ziph at Horesh.

If anyone should arise to pursue you and seek your life, may the life of your majesty be bound up with the LORD your God in a bundle of the living, and may he sling out the lives of your enemies from the pocket of a sling.

Now, don't let my blood fall to the ground away from the LORD's presence. Indeed, the king of Israel has come out to seek a single flea, like someone hunts a partridge in the mountains."
