In the fifth century B.C. a prophet named Zechariah declared that the Messiah would be betrayed for the price of a slave—thirty pieces of silver, according to Jewish law-and also that this money would be used to buy a burial ground for Jerusalem's poor foreigners (Zechariah 11:12-13). Bible writers and secular historians both record thirty pieces of silver as the sum paid to Judas Iscariot for betraying Jesus, and they indicate that the money went to purchase a "potter's field," used—just as predicted—for the burial of poor aliens (Matthew 27:3-10).
