Matthew 24:45 is the parallel account of the same parable of the faithful servant, directly relating to Peter’s question.

1 Peter 4:7, written by Peter, calls all believers to be alert—extending the warning beyond the original disciples.

Mark 13:37 answers Peter’s question by stating that the command to watch is for everyone, not just the disciples.

Mark 14:37 shows Peter later failing to watch, contrasting his earlier question about who needs to be ready.

1 Peter 5:8 similarly urges alertness against the devil, showing Peter’s consistent teaching on watchfulness.
