[2:30] 1 sn To see Jesus, the Messiah, is to see God’s salvation.
[2:31] 2 sn Is the phrase all peoples a reference to Israel alone, or to both Israel and the Gentiles? The following verse makes it clear that all peoples includes Gentiles, another key Lukan emphasis (Luke 24:47; Acts 10:34-43).
[3:6] 4 sn A quotation from Isa 40:3-5. Though all the synoptic gospels use this citation from Isaiah, only Luke cites the material of vv. 5-6. His goal may well be to get to the declaration of v. 6, where all humanity (i.e., all nations) see God’s salvation (see also Luke 24:47).
