'Wait' in the Bible

Thus saith the LORD of hosts, I remember that which Amalek did to Israel, how he laid wait for him in the way, when he came up from Egypt.

And Saul came to a city of Amalek, and laid wait in the valley.

That all of you have conspired against me, and there is none that sheweth me that my son hath made a league with the son of Jesse, and there is none of you that is sorry for me, or sheweth unto me that my son hath stirred up my servant against me, to lie in wait, as at this day?

And Saul said unto him, Why have ye conspired against me, thou and the son of Jesse, in that thou hast given him bread, and a sword, and hast inquired of God for him, that he should rise against me, to lie in wait, as at this day?
