An interesting passage which connects salvation with knowledge and revelation is the “Song of Simeon” in Luke 2:29-32. Like the hymn of Zechariah (the Benedictus, Lk 1:67-79), it functions in the narrative as a prophetic oracle. There are actually two oracles uttered by Simeon, the other being addressed to Mary in vv. 34-35. All of the canticles, or hymns, in the Lukan Infancy narrative, draw heavily upon the Old Testament Scriptures, quoting or alluding to various passages in nearly every line. The very poetry, and the underlying mode of expression, has assimilated the language of the Old Testament Songs, Psalms and poetic oracles of the Prophets. The Song of Simeon is comprised of four lines. In the first line (v. 29), Simeon addresses himself to God:
“Now you (can) loose your slave from (his bonds), O Master, according to your utterance, in peace”
The second line (v. 30), in the context of the narrative, relates to Simeon’s revelatory experience of seeing the child Jesus:
“(in) that [i.e. because] my eyes saw your salvation”
The third line (v. 31) connects this revelation back to the prophecies and promises in the Old Testament, the (old) covenant between God and his people:
“which you made ready down upon the face [i.e. in the presence] of all the people”
The fourth line (v. 32) indicates the goal and purpose of this revelation:
“a light unto the uncovering of the nations, and (the) honor/splendor of your people Yisrael”
The theme of salvation is emphasized in the first two lines:
“Now you (can) loose your slave from (his bonds), O Master, according to your utterance, in peace,
(in) that [i.e. because] my eyes saw your salvation [swthri/a]”
The narrative context would associate the words a)polu/w (“loose from [bondage]”) and dou=lo$ (“slave”) with Simeon’s earthly life, lived in service to God (YHWH) as his Lord/Master (despo/th$), that is, the lord/master of the house who is the owner of the slave. However, the hymn itself can (and should) also be read more generally in terms of salvation from slavery to sin, etc, which is otherwise associated with the birth of Jesus in Lk 1:77, and more directly in Matt 1:21. The mention of peace [ei)rh/nh] also well fits the idea of salvation.
In the last two lines the theme of revelation is emphasized:
“which you made ready down upon the face [i.e. in the presence] of all the people:
a light unto the uncovering of the nations, and (the) honor/splendor of your people Yisrael”
This is already suggested by the use of ei&dw (“see”) and o)fqalmoi/ (“eyes”) in v. 30; the verb ei&dw (oi@da) in Greek is essentially interchangeable with ginw/skw (“know”) and often indicates knowing as well as seeing. The expression kata\ pro/swpon (“down on the face”, “against the face”, i.e. “before the face”) also suggests something that is seen; the word translated “face” (pro/swpon) literally means “toward the eye”, i.e. before one’s eyes, facing, and so the face or “appearance” of a person, etc. For the words fw=$ (“light”) and a)poka/luyi$ (“taking the cover from”, “uncovering”) used for revelation, cf. Part 2 of the series “Gnosis and the New Testament”. The noun do/ca refers to the esteem or honor which a person receives, or which is due to that person (especially God), often described in terms of visual splendor (light-imagery, etc); it is frequently associated with divine revelation in the New Testament. For more on the connection between salvation and revelation, cf. Part 3 in “Gnosis and the New Testament”.
I discuss the Song of Simeon elsewhere, examining each verse (each line) in considerable detail.
As my translation above is an extremely literal (glossed) rendering, the rhythm and feel of the poetry has been obscured; here below, in closing, is a more poetic rendering:
“Now, Master, you can release your slave, according to your word, in peace,
(now) that my eyes have seen your salvation
which you prepared before the face of all (the) people—
a light to uncover (for) the nations,
and (the) splendor of your people Israel.”
