George Leo Haydock

For nowhere doth he take hold of the Angels. [4] Literally, that he apprehendeth, or layeth hold on the Angels; that is, according to the common interpretation, we nowhere find that he hath united their nature to his divine person to save them, though a great part of them had also sinned and fallen from heaven. But he taketh the seed of Abraham; i.e. he became man of the seed or race of Abraham, to redeem or save mankind. (Witham) — Nowhere, &c. That is, he never took upon him the nature of Angels, but that of the seed of Abraham. (Challoner)
