“And Ephron answered Abraham, saying unto him,”
King James Version (KJV)
23:13 I will give thee money for the field - It was not in pride that Abraham refused the gift; but In justice. Abraham was rich in silver and gold, and therefore would not take advantage of Ephron's generosity. In prudence. He would pay for it, lest Ephron, when this good humour was over, should upbraid him with it.
23:15 The land is worth four hundred shekels of silver - About fifty pounds of our money, but what is that between me and thee? - He would rather oblige his friend than have so much money.
