A.T. Robertson Commentary Ephesians 5:29

"for no man ever hated his own flesh; but nourisheth and cherisheth it, even as Christ also the church;" — Ephesians 5:29 (ASV)

Nourisheth (εκτρεφε). Old compound with perfective sense of εκ (to nourish up to maturity and on). In N.T. only here and 6:4.

Cherisheth (θαλπε). Late and rare word, once in a marriage contract in a papyrus. In N.T. only here and 1 Thessalonians 2:7. Primarily it means to warm (Latin foveo), then to foster with tender care as here.

Even as Christ also (καθως κα ο Χριστος). Relative (correlative) adverb pointing back to ουτως at the beginning of the sentence (verse 28) and repeating the statement in verse 25.
