Summary

Adam Clarke Commentary and critical notes on the Bible… (1800s)

If a brother, who had married a wife, died without children, the eldest brother was to take the widow, and raise up a family to the brother deceased; and he had a right to redeem the inheritance, if it had been alienated. But if the person who had the right of redemption would not take the woman, she was to pull off his shoe and spit in his face, and he was ever after considered as a disgraced man. In the present case the shoe only is taken off, probably because the circumstances of the man were such as to render it improper for him to redeem the ground and take Ruth to his wife

Thou must buy it also of Ruth - More properly, Thou wilt also acquire Ruth. Thou canst not get the land without taking the wife of the deceased and then the children which thou mayest have shall be reputed the children of Mahlon, thy deceased kinsman.
Verse 6
I cannot redeem it for myself - The Targum gives the proper sense of this passage: "And the kinsman said, On this ground I cannot redeem it, because I have a wife already; and I have no desire to take another, lest there should be contention in my house, and I should become a corrupter of my inheritance.

God alone can give thee a full reward for thy kindness to thy husband and mother-in-law, and he will do it, because thou art come to trust under his wings - to become a proselyte to his religion. The metaphor is taken from the young of fowls, who, seeing a bird of prey, run to their mother to be covered by her wings from danger, and also to take shelter from storms, tempests, cold, etc. It is evident from this that Ruth had already attached herself to the Jewish religion.
