A.T. Robertson Commentary 1 Corinthians 11:13

"Judge ye in yourselves: is it seemly that a woman pray unto God unveiled?" — 1 Corinthians 11:13 (ASV)

Is it seemly? (πρεπον εστιν; ). Periphrastic present indicative rather than πρεπε. See on Mt 3:15. Paul appeals to the sense of propriety among the Corinthians.
