Markus 13:23

13:23 Be careful! I have told you everything ahead of time.

Markus 13:35-37

13:35 Stay alert, then, because you do not know when the owner of the house will return – whether during evening, at midnight, when the rooster crows, or at dawn – 13:36 or else he might find you asleep when he returns suddenly. 13:37 What I say to you I say to everyone: Stay alert!”

Markus 14:37-38

14:37 Then ¹  he came and found them sleeping, and said to Peter, “Simon, are you sleeping? Couldn’t you stay awake for one hour? 14:38 Stay awake and pray that you will not fall into temptation. The spirit is willing, but the flesh is weak.”

[14:37]  ¹ tn Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the narrative.
