I thought to inform you of it, saying, ‘Buy it in the presence of those who are sitting here, and in the presence of the elders of my people.’ If you will redeem it, redeem it, but if you will not redeem it, then tell me, so that I know. For there is no one to redeem it besides you, and I am after you.”

And he said, “I will redeem it.” Bible

“to inform you of it.” The Hebrew text uses an idiom, “uncover your ear.”

“For there is no one to redeem it besides you.” The Mosaic Law only stipulated that a brother of the deceased would marry the widow, but it is reasonable to assume that if no brother existed that the next closest relative would act as the kinsman-redeemer unless, as in this case, he turned it down and another person acted as the kinsman-redeemer. Thus the door was opened for Boaz to be the kinsman-redeemer for Ruth and Naomi.
