Finally, my brethren, be strong in the Lord, and in the power of his might.
My brethren. So C G g, Vulgate. But 'Aleph (') A B Delta omit. The phrase occurs nowhere else (see, however, Ephesians 6:23): if genuine, it is appropriate in the close of the letter, where he is urging his fellow-soldiers to the good fight. 'Aleph (') A B for 'finally' х to (G3588) loipon (G3063): C Delta G] read 'henceforward,' or 'from henceforth' х tou (G3588) loipou (G3064)] (Galatians 6:17).
Be strong, х endunamousthe (G1743)] - 'be strengthened.'
In the power (in action) of his might (passive) - Christ's might (2 Corinthians 12:9): as in Ephesians 1:19 it is the Father's.
