'Buy' in the Bible

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.

And Boaz said, On the 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.

And he that had the right of redemption said to Boaz, Buy for thyself; and he drew off his sandal.
