Amminadab begat Nahshon - The Targum adds, "And Nahshon was chief of the house of his father in the tribe of Judah."

Nahshon begat Salmon - In the Hebrew it is שלמה Salmah, which Houbigant thinks was an error of an ancient scribe, before any final letters were acknowledged in the Hebrew alphabet: for then the word would be written שלמון Salmon, which a scribe, after final letters were admitted, might mistake for שלמה Salmah, and so write it, instead of שלמון Salmon, the ו vau and final nun in conjunction (ון) bearing some resemblance to ה.

The Targum calls him "Salmah the Just; he was the Salmah of Beth-lehem and Netopha, whose sons abolished the watches which Jeroboam set over the highways; and their works and the works of their father were good in Netopha."

And Amminadab begat Nahshon,.... The prince of the tribe of Judah, as the Targum adds; and so he was when the Israelites were come out of Egypt, and were in the wilderness at the time of the dedication of the altar, Numbers 7:12 called Nahsson, Matthew 1:4, and Nahshon begat Salmon; or, as in the Hebrew text, Salmah, and in 1 Chronicles 2:11, Salma; and yet in the verse following Salmon, as we read it.

And Amminadab begat Nahshon, and Nahshon begat Salmon,

Salmon: or, Salmah

4:13-22 Ruth bore a son, through whom thousands and myriads were born to God; and in being the lineal ancestor of Christ, she was instrumental in the happiness of all that shall be saved by him; even of us Gentiles, as well as those of Jewish descent. She was a witness for God to the Gentile world, that he had not utterly forsaken them, but that in due time they should become one with his chosen people, and partake of his salvation. Prayer to God attended the marriage, and praise to him attended the birth of the child. What a pity it is that pious language should not be more used among Christians, or that it should be let fall into formality! Here is the descent of David from Ruth. And the period came when Bethlehem-Judah displayed greater wonders than those in the history of Ruth, when the outcast babe of another forlorn female of the same race appeared, controlling the counsels of the Roman master of the world, and drawing princes and wise men from the east, with treasures of gold, and frankincense, and myrrh to his feet. His name shall endure for ever, and all nations shall call Him blessed. In that Seed shall all the nations of the earth be blessed.
