'Buy' in the Bible

And I thought to disclose it unto thee, saying, Buy it before them that sit here, and before the elders of my people. If thou wilt redeem it, redeem it: but if thou wilt not redeem it, then tell me, that I may know; for there is none to redeem it besides thee; and I am after thee. And he said, I will redeem it.

Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

So the near kinsman said unto Boaz, Buy it for thyself. And he drew off his shoe.
