'Buy' in the Bible

and I said, I uncover thine ear, saying, Buy before the inhabitants, and before the elders of my people; if thou dost redeem -- redeem, and if none doth redeem -- declare to me, and I know, for there is none save thee to redeem, and I after thee.' And he saith, I redeem it.'

And the redeemer saith to Boaz, 'Buy it for thyself,' and draweth off his sandal.
