The family of Ram (1 Chronicles 2:10-12), traced down through six members of Jesse. - This genealogy is also to be found in Ruth 1 Chronicles Ruth 4:19-21; but only here is Nahshon made more prominent than the others, by the addition, "prince of the sons of Judah." Nahshon was a prince of Judah at the exodus of the Israelites from Egypt (Numbers 1:7; Numbers 2:3; Numbers 7:12). Now between him, a contemporary of Moses, and Pharez, who at the immigration of Jacob into Egypt was about fifteen years old, lies a period of 430 years, during which the Israelites remained in Egypt. For that time only three names - Hezron, Ram, and Amminidab - are mentioned, from which it is clear that several links must have been passed over. So also, from Nahshon to David, for a period of over 400 years, four generations - Salma, Boaz, Obed, and Jesse - are too few; and consequently here also the less famous ancestors of David are omitted. שׂלמא is called in Ruth 4:20-21, שׁלמה and שׂלמון. In 1 Chronicles 2:13-15, seven sons and two daughters of Jesse, with those of their sons who became famous (1 Chronicles 2:16, 1 Chronicles 2:17), are enumerated. According to 1 Samuel 17:12, Jesse had eight sons. This account, which agrees with that in 1 Samuel 16:8-12, may be reconciled with the enumeration in our verse, on the supposition that one of the sons died without posterity. In 1 Samuel 16:6. and 1 Chronicles 17:13, the names of the eldest three - Eliab, Abinadab, and Shammah - occur. Besides ישׁי, we meet with the form אשׁי (1 Chronicles 2:13); and the name שׁמּה is only another form of שׁמעה, which is found in 2 Samuel 13:3 and in 1 Chronicles 20:7, and is repeated in 2 Samuel 13:32 and 2 Samuel 21:21 in the Kethibh (שׁמעי). The names of the other three sons here mentioned (1 Chronicles 2:14 and 1 Chronicles 2:15) are met with nowhere else.

Jether. Jether is essentially the same with Ithra, the latter only having the addition of an {aleph,} and it is probable, that he was an Ishmaelite by birth but an Israelite by religion.
