Very interesting stuff.
Another potentially important track in the OT texts can be found in the Exodus stories and allusions which (1) combine the "wind" and "sea / abyss" motives and (2) recycle old cosmogonic mythemes (from the Baal / Yamm or Marduk / Tiamat cycles for instance: Exodus 15:8ff; cf. Isaiah 11:15; 17:13; 63:11ff; Psalm 18:15; Job 26:13). The avian motif (which combines with the Mesopotamian-like winged "cherubim" in Psalm 18:10 // 2 Samuel 22) is less apparent in the OT (cf. also Zechariah 5:9) but may resurge in the connection of the Spirit with the dove in the Synoptic baptism scene and perhaps in the "shadow" theme in the Annunciation and Transfiguration (but then there is also the cloud motif which points back to the Exodus tradition again). A fascinating network of images anyway.
