And I thought I would apprise thee of it and say, Buy it in the presence of the inhabitants, and in the presence of the elders of my people. If thou wilt redeem it, redeem; but if thou wilt not redeem, tell me, that I may know; for there is none to redeem besides thee; and I am after thee. And he said, I will redeem it.
