Hebrews 5:12-14 For when by the time you ought to be teachers, you have need that one teach you again of the first principles of the oracles of God; and have become such as have need of milk, and not of strong food.

12 G2532 For G1063 G1223 when by G5550 the time G3784 you ought G1511 to be G1320 teachers, G2192 you have G5532 need G1321 that one teach G5209 you G3825 again G5101 of G746 the first G4747 principles G3051 of the oracles G2316 of God; G2532 and G1096 have become such as G2192 have G5532 need G1051 of milk, G2532 and G3756 not G4731 of strong G5160 food.

13 G1063 For G3956 every one G3348 that uses G1051 milk G552 is unskilled G3056 in the word G1343 of righteousness: G1063 for G2076 he is G3516 a baby.

14 G1161 But G4731 strong G5160 food G2076 belongs G5046 to them that are of full age, G2192 even those who G1223 by reason of G1838 use G2192 have G145 their senses G1128 exercised G4314 to G1253 discern G5037 both G2570 good G2532 and G2556 evil.
