²⁰ Brothers and sisters, do not be children in your thinking; rather, be infants in evil, but in thinking be adults.^(A)

¹⁴ We must no longer be children, tossed to and fro and blown about by every wind of doctrine by people’s trickery, by their craftiness in deceitful scheming;^{(A) 15} but speaking the truth in love, we must grow up in every way into him who is the head, into Christ,^(B)
