Mark 13:35-37
35 So, stay at your post, watching. You have no idea when the homeowner is returning, whether evening, midnight, cockcrow, or morning. 36 You don't want him showing up unannounced, with you asleep on the job. 37 I say it to you, and I'm saying it to all: Stay at your post. Keep watch."

I won’t be asleep on the job!
