'Lying in wait' in the Bible

But Paul's sister's son hearing of the lying-in-wait, happening to be near, and coming into the castle, - reported it unto Paul.

Thou, therefore, do not be persuaded by them, for there are lying in wait for him, from among them, more than forty men, - who, indeed, have bound themselves under a curse, neither to eat nor drink, till they have killed him; and, now, are they ready, awaiting the promise, from thee.
