Rute 4:20

Nahshon was the prince of the children of Judah in the wilderness. (See Números 1:7, &c).

Salmon — Heb., Salmah, though called Salmon in the next verse. In 1 Crônicas 2:11 he is called Salma. Salmon may very probably have been one of the two spies sent to Jericho, who having been sheltered by Rahab, had repaid her kindness by marrying her.

It has been observed above that the smallness of the number of the generations hardly suits the long period of years here implied, and on the whole we are disposed to believe that some links of the chain have been dropped, and if so, then doubtless in the period before Boaz. Thus we may suppose that we have here the distinguished names, others of less note being passed over. Unless this is done we are forced to increase largely the average length of a generation, and suppose that most of these generations were children of their fathers’ old age. We know from 1 Reis 6:1 that from the Exodus to the fourth year of Solomon was 480 years. If we deduct from this forty years for the wanderings in the desert, then, seeing that David died at the age of seventy, we have for the period from the entrance into Canaan to the birth of David, 480-40-70-4 = 366 years. But if Rahab bears Boaz to Salmon only a few years after the beginning of this period, we have to cover nearly 366 years with three generations, Boaz, Obed, Jesse, which entails upon us the conclusion that each of the above three begat the specified son at the age of over a hundred, and that Salmon was also well advanced in years at his marriage. This, however, seems hardly credible, and the theory that one or two generations have dropt from the list is, at any rate, reasonable.
