Markus 9:4

9:4 Then Elijah appeared before them along with Moses, ¹  and they were talking with Jesus.

Markus 9:29

9:29 He told them, “This kind can come out only by prayer.” ² 

Markus 13:36

13:36 or else he might find you asleep when he returns suddenly.

[9:4]  ¹ sn Commentators and scholars discuss why Moses and Elijah are present. The most likely explanation is that Moses represents the prophetic office (Acts 3:18-22) and Elijah pictures the presence of the last days (Mal 4:5-6), the prophet of the eschaton (the end times).

[9:29]  ² 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.
