A.T. Robertson Commentary Ephesians 3:14

"For this cause I bow my knees unto the Father," — Ephesians 3:14 (ASV)

I bow my knees (καμπτω τα γονατα μου). He now prays whether he had at first intended to do so at 3:1 or not. Calvin supposes that Paul knelt as he dictated this prayer, but this is not necessary. This was a common attitude in prayer (Luke 22:41; Acts 7:40; Acts 20:36; Acts 21:5), though standing is also frequent (Luke 18:11,13).
