Genesis 23:15-16 “My lord, listen to me; the land is worth four hundred shekels of silver. What is that between you and me? So bury your dead.” And Abraham listened to Ephron; and Abraham weighed out the silver for Ephron which he had named in the hearing of the sons of Heth, four hundred shekels of silver, currency of the merchants.
Zechariah 11:13 And the Lord said to me, “Throw it to the potter”—that princely price they set on me. So I took the thirty pieces of silver and threw them into the house of the Lord for the potter.
Zechariah 13:9 I will bring the one–third through the fire, Will refine them as silver is refined, And test them as gold is tested. They will call on My name, And I will answer them. I will say, ‘This is My people’; And each one will say, ‘The Lord is my God.’”
