Ruth 4:4, 8

So I thought I would tell you of it and say, ‘Buy it in the presence of those sitting here and in the presence of the elders of my people.’ If you will redeem it, redeem it. But if you will not, tell me, that I may know, for there is no one besides you to redeem it, and I come after you.” And he said, “I will redeem it.”

So when the redeemer said to Boaz, “Buy it for yourself,” he drew off his sandal.
