Luke 3:31-32

3:31 the son of Melea, the son of Menna, the son of Mattatha, the son of Nathan, the son of David, 3:32 the son of Jesse, the son of Obed, the son of Boaz, the son of Sala, the son of Nahshon,

sn The use of Nathan here as the son of David is different than Matthew, where Solomon is named. Nathan was David’s third son. It is not entirely clear what causes the difference. Some argue Nathan stresses a prophetic connection, but it is not clear how (through confusion with the prophet Nathan?). Others note the absence of a reference to Jeconiah later, so that here there is a difference to show the canceling out of this line. The differences appear to mean that Matthew’s line is a “royal and physical” line, while Luke has a “royal and legal” line.

sn The mention of David begins a series of agreements with Matthew’s line. The OT background is 1 Chr 2:1-15 and Ruth 4:18-22.

tc The reading Σαλά (Sala, “Sala”) is found in the best and earliest witnesses (Ì4 א* B sys sa). Almost all the rest of the mss (א2 A D L Θ Ψ 0102 [Ë1,13] 33 Ï latt syp,h bo) have Σαλμών (Salmwn, “Salmon”), an assimilation to Matt 1:4-5 and 1 Chr 2:11 (LXX). “In view of the early tradition that Luke was a Syrian of Antioch it is perhaps significant that the form Σαλά appears to embody a Syriac tradition” (TCGNT 113).
