Hebrews 5:7-13

who in the days of his flesh offered up both prayers and supplications, with loud crying and tears, to the one who was able to save him from death, and he was heard as a result of his reverence. Although he was a son, he learned obedience from what he suffered, and being perfected, he became the source of eternal salvation to all those who obey him, being designated by God a high priest according to the order of Melchizedek. Concerning this we have much to say and it is difficult to explain, since you have become sluggish in hearing. For indeed, although you ought to be teachers by this time, you have need of someone to teach you again the beginning elements of the oracles of God, and you have need of milk, not solid food. For everyone who partakes of milk is unacquainted with the message of righteousness, because he is an infant.
