A single witness may not testify ¹  against another person for any trespass or sin that he commits. A matter may be legally established ²  only on the testimony of two or three witnesses.

(Now this used to be the customary way to finalize a transaction involving redemption in Israel: ¹  A man would remove his sandal and give it to the other party. ²  This was a legally binding act ³  in Israel.)

So I am legally informing you: ¹  Acquire it before those sitting here and before the leaders of my people! ²  If you want to exercise your right to redeem it, then do so. ³  But if not, then tell me ⁴  so I will know. ⁵  For you possess the first option to redeem it; I am next in line after you.” ⁶  He replied, “I will redeem it.”
