Matthew Henry on Ruth 4:1-8
Here, 1. Boaz calls a court immediately. It is probable he was himself one of the elders (or aldermen) of the city; for he was a mighty man of wealth. Perhaps he was father of the city, and sat chief; for he seems here to have gone up to the gate as one having authority, and not as a common person; like Job, Job 29:7, etc. We cannot suppose him less than a magistrate in his city who was grandson to Nahshon, prince of Judah; and his lying at the end of a heap of corn in the threshing-floor the night before was not at all inconsistent, in those days of plainness, with the honour of his sitting judge in the gate. But why was Boaz so hasty, why so fond of the match? Ruth was not rich, but lived…

HE REFUSES THE REDEMPTION. (Rut 4:6-8)

This right, therefore, was renounced and assigned in favor of Boaz, in the way of whose marriage with Ruth the only existing obstacle was now removed.
Adam Clarke on Ruth 4:6
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. Do thou redeem it, for thou hast no wife; for I cannot redeem it." This needs no comment. But still the gloss of the Targum has no foundation in the law of Moses. See the law, Deu 25:5-9.
John Gill on Ruth 4:6
And the kinsman said, I cannot redeem it for myself,.... On such a condition, because he had a wife, as the Targum suggests; and to take another would, as that intimates, tend to introduce contention into his family, and make him uncomfortable; so Josephus says (h), he had a wife and children, for that reason it was not convenient for him to take the purchase on such a condition:
lest I mar my own inheritance; he considered, that as he had a wife and children already and as he might have more by marrying Ruth, his family expenses would be increased, and his estate diminished; and what would remain must be divided among many, and this estate in particular go to Ruth's firstborn, whereby his…
