'Ambush' in the Bible

Then Saul came up to the city of Amalek and set an ambush in the wadi.

For all of you have conspired against me, and {no one discloses to me} the {making} [of an agreement] between my son and the son of Jesse! None of you have had sympathy for me or {disclosed to me} [that] {my son commissioned my servant against me to ambush me} as [has been done] this day!"

Then Saul said to him, "Why did you conspire against me, you and the son of Jesse, when you gave to him bread and a sword, and by inquiring of God for him so that he might arise against me to ambush [me] as [has been done] this day?"
