Mark 9:29

He told them, “This kind can come out only by prayer.” ¹ 

1Ki 17:20-22; 2Ki 4:33,34; Da 9:3; Mt 12:45; Mt 17:21; Lu 11:26; Ac 9:40,41; Ac 14:23; 1Co 9:27; 2Co 6:5; 2Co 11:27; 2Co 12:8; Eph 6:18; Jas 5:15

¹ tc Most witnesses, even early and excellent ones (Ì^45vid א² A C D L W Θ Ψ Ë^1,13 33 Ï lat co), have “and fasting” (καὶ νηστείᾳ, kai nhsteia) after “prayer” here. But this seems to be a motivated reading, due to the early church’s emphasis on fasting (TCGNT 85; cf., e.g., 2 Clem. 16:4; Pol. Phil 7:2; Did. 1:3; 7:4). That the most important witnesses (א* B), as well as a few others (0274 2427 k), lack καὶ νηστείᾳ, when a good reason for the omission is difficult to find, argues strongly for the shorter reading.
