A.T. Robertson Commentary Luke 2:28

"then he received him into his arms, and blessed God, and said," — Luke 2:28 (ASV)

Then he (κα αυτος). Κα as in 2:21. Αυτος, emphatic subject, he after the parents.

Arms (αγκαλας). Old Greek word, here only in the N.T. It means the curve or inner angle of the arm.
