Rut 4:3

Boaz Marries Ruth - Ruth 4 To redeem the promise he had given to Ruth, Boaz went the next morning to the gate of the city, and calling to the nearer redeemer as he passed by, asked him, before the elders of the city, to redeem the piece of land which belonged to Elimelech and had been sold by Naomi; and if he did this, at the same time to marry Ruth, to establish the name of the deceased upon his inheritance (Rut 4:1-5). But as he renounced the right of redemption on account of the condition attached to the redemption of the field, Boaz undertook the redemption before the assembled people, together with the obligation to marry Ruth (Rut 4:6-12). The marriage was blessed with a son, who became the father of Jesse, the father of David (Rut 4:13-17). The book closes with a genealogical proof of the descent of David from Perez (Rut 4:18-22).

In this chapter we have the wedding between Boaz and Ruth, in the circumstances of which there was something uncommon, which is kept upon record for the illustration, not only of the law concerning the marrying of a brother's widow (Deu 25:5, etc.), for cases help to expound laws, but of the gospel too, for from this marriage descended David, and the Son of David, whose espousals to the Gentile church were hereby typified. We are here told, I. How Boaz got clear of his rival, and fairly shook him off (Rut 4:1-8). II. How his marriage with Ruth was publicly solemnized, and attended with the good wishes of his neighbours (Rut 4:9-12). III. The happy issue that descended from this marriage, Obed, the grandfather of David (Rut 4:13-17). And so the book concludes with the pedigree of David (Rut 4:18-22). Perhaps it was to oblige him that the blessed Spirit directed the inserting of this story in the sacred canon, he being desirous that the virtues of his great-grandmother Ruth, together with her Gentile extraction and the singular providences that attended her, should be transmitted to posterity.

4:3 Naomi . . . is selling the land: Naomi probably did not have control of Elimelech’s ancestral land, though she did have legal title. She was selling the right to redeem it, or buy it back, from whoever was currently using it.
