2 Bible Verses about Drowsiness

as it has been written [Isa. 19:10], "God gave them a spirit of numbness [i.e., they developed a spiritual insensitivity to God and His word]. [He gave them] eyes to see with [but they would not look], and ears to hear with [but they did not listen]. And they still have this spirit."

And He went on ahead a short distance and fell face-down and prayed, "My Father, allow this cup [i.e., of suffering] to pass away from me if it is [at all] possible; nevertheless, let it not be what I want, but what You want [for me]." 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? 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]."read more.
He [then] went away a second time and prayed, "My Father, if this [cup of suffering] cannot pass away unless I drink it [i.e., experience the suffering], [then] let what You want be done." And He came [back] again and found them asleep, because they had not been able to keep their eyes open.
