'Ambush' in the Bible

Saul proceeded to the city of Amalek, where he set an ambush in the wadi.

For all of you have conspired against me! No one informs me when my own son makes an agreement with this son of Jesse! Not one of you feels sorry for me or informs me that my own son has commissioned my own servant to hide in ambush against me, as is the case today!"

Saul said to him, "Why have you conspired against me, you and this son of Jesse? You gave him bread and a sword and inquired of God on his behalf, so that he opposes me and waits in ambush, as is the case today!"

Look, my father, and see the edge of your robe in my hand! When I cut off the edge of your robe, I didn't kill you. So realize and understand that I am not planning evil or rebellion. Even though I have not sinned against you, you are waiting in ambush to take my life.
