'Pound' in the Bible

Even though you pound a [hardened, arrogant] fool [who rejects wisdom] in a mortar with a pestle like grain,Yet his foolishness will not leave him.

The food you eat each day shall be [measured] by weight, twenty shekels, to be eaten daily at a set time.

Then Mary took a pound of very expensive perfume of pure nard, and she poured it on Jesus’ feet and wiped His feet with her hair; and the house was filled with the fragrance of the perfume.
