'Buy' in the Bible

I thought I should inform you: Buy it back in the presence of those seated here and in the presence of the elders of my people. If you want to redeem it, do so. But if you do not want to redeem it, tell me so that I will know, because there isn’t anyone other than you to redeem it, and I am next after you.”“I want to redeem it,” he answered.

Then Boaz said, “On the day you buy the land from Naomi, you will also acquire Ruth the Moabitess, the wife of the deceased man, to perpetuate the man’s name on his property.”

So the redeemer removed his sandal and said to Boaz, “Buy back the property yourself.”
