וַיִּבְרָא אֱלֹהִים,..... וְאֵת כָּל-עוֹף כָּנָף לְמִינֵהוּ,
v'yeevrEH' ehloHEEM...v'eyt kol 'ohf kaNAHF l'miNEYoo
"And Elohim created...and all winged birds, according to their kind."
This is also the word used to describe the wings of the cherubim on the Ark cover in the most holy place in Sh'mot 37:
וַיִּהְיוּ הַכְּרֻבִים פֹּרְשֵׂי כְנָפַיִם לְמַעְלָה
vayeeHOO hak'rooVEEM porSEY k'naFAYeem l'maLEH
"The cherubim spread wings up high"
There also seems to be a connection to clothing; especially with the corners, borders or edges of a garment, that the tzit-tzit are to be attached to. From B'midbar 15:38
וְנָתְנוּ עַל-צִיצִת הַכָּנָף, פְּתִיל תְּכֵלֶת.
vnat'NOO al tzit-tzit hakahNAF, p'teel tekhLET
"And [they] will give/set upon the fringe of the corner a thread/cord of blue/violet."
It seems that under Adonai's wings, it is a place of protection, as in Tehillim 91:4:
v'TAHchat k'naFAI techSEH
"And under His wings, you will seek refuge"
