And [when] He came [back] to where His disciples were and found them asleep, He said to Peter, “What [is this], could you not remain alert with me [in prayer] for one hour?
Now Peter and those with him [i.e., James and John] had been very sleepy, but became wide awake when they saw the splendor of Jesus and the two men standing with Him.
Be alert and pray, so that you do not give in to temptation; the spirit [of a person] is truly willing [i.e., to do a certain thing], but his physical nature is [often too] weak [to carry it out].”
