'Lying in wait' in the Bible

lying in wait for Him, to catch something out of His mouth.

And the son of Paul's sister, hearing of their lying in wait, going and entering into the castle, reported it to Paul.

Be not, therefore, persuaded by them; for more than forty men of them are lying in wait for him; who, indeed, bound themselves under a curse, neither to eat nor drink, till they should kill him; and now they are ready, expecting the promise from you."
