And I beseech you, brethren, suffer the word of exhortation: for I have written a letter unto you in few words.
Suffer the word. The Hebrews not being the section assigned to Paul (but the Gentiles), he uses gentle entreaty rather than authoritative command.
Few words - compared with what might be said on so important a subject. Few, in an letter more a treatise than an letter (cf. 1 Peter 5:12). On the seeming inconsistency with Galatians 6:11, cf. note.
