'Spare' in the Bible

Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.

Ask your own servants; they can tell you! May my servants find favor in your sight, for we have come at the time of a holiday. Please provide us -- your servants and your son David -- with whatever you can spare."
