Hebrews 5:13

13 For everyone who partakes only of milk is not accustomed to the word of righteousness, for he is an ^ainfant.

1 Corinthians 13:11

11 When I was a child, I used to speak like a child, think like a child, reason like a child. When I ¹became a man, I did away with childish things.

20 ^aBrothers, ^bdo not be children in your thinking; rather in evil ^cbe infants, but in your thinking be mature.
