A.T. Robertson Commentary Matthew 10:32

"Every one therefore who shall confess me before men, him will I also confess before my Father who is in heaven." — Matthew 10:32 (ASV)

Shall confess me (ομολογησε εν εμο). An Aramaic idiom, not Hebrew, see also Lu 12:8. So also here, "him will I also confess" (ομολογησω κ'αγω εν αυτω). Literally this Aramaic idiom reproduced in the Greek means "confess in me," indicating a sense of unity with Christ and of Christ with the man who takes the open stand for him.
