Hebrews 5:13

8 through being a Son, did learn by the things which he suffered -- the obedience,

9 and having been made perfect, he did become to all those obeying him a cause of salvation age-during,

10 having been addressed by God a chief priest, according to the order of Melchisedek,

11 concerning whom we have much discourse and of hard explanation to say, since ye have become dull of hearing,

12 for even owing to be teachers, because of the time, again ye have need that one teach you what [are] the elements of the beginning of the oracles of God, and ye have become having need of milk, and not of strong food,

13 for every one who is partaking of milk [is] unskilled in the word of righteousness -- for he is an infant,

14 and of perfect men is the strong food, who because of the use are having the senses exercised, unto the discernment both of good and of evil.
