Matthew Poole and continuators on Ephesians 6:10

10▪ Finally, my brethren, be strong in the Lord and in the power of his might .

Or strengthen your selves, i. e. be courageous, and constant in the practice of your duty against the Devil, and all his assaults.

Not in your selves, but in the Lord Jesus Christ in whom your strength lies, and from whom by Faith ye may obtain it, see Phil. 4.13. and 2 Tim. 2.1.

Or mighty power, see ch. 1.19. q. d. though your own strength be but weakness, yet Christ's power is mighty, and he can communicate enough to you.
