2 Corinthians 13:11

Finally, brethren, farewell. — The word (literally, rejoice) was the natural close of a Greek letter, and is therefore adequately represented by the English “farewell,” if only we remember that it was used in all the fulness of its meaning. “Rejoice — let that be our last word to you.”

Be perfect. — Better, as before, restore yourselves to completeness; amend yourselves. In the words “be of good comfort” (better, perhaps, be comforted, with the implied thought that the comfort comes through accepting his word of counsel — see Note on Acts 4:36) we trace an echo of what he had said in the opening of the Epistle, as to the “comfort” which had been given to him (2 Corinthians 1:4; 2 Corinthians 1:7). Paraclesis in its two-fold aspect is, in fact, the key-note of the whole Epistle. Taking the verb and the noun together, the word occurs twenty-eight times in it.

Be of one mind. — The phrase was one specially characteristic of St. Paul’s teaching (Romans 15:6; Philippians 2:2; Philippians 3:16; Philippians 4:2). His thoughts are apparently travelling back to the schisms over which he had grieved in 1 Corinthians 1-3, and to which he had referred in 2 Corinthians 12:20. What he seeks is the restoration of unity of purpose, and with that of inward and outward peace. If these conditions were fulfilled, the “God of love and peace would assuredly be with them,” for peace rests ever upon the son of peace (Luke 10:6).
