Hebrews 5:13

For every one that useth milk is unskilful in the word of righteousness: for he is a babe.

For everyone who lives on milk is not experienced in the word of righteousness, for he is a baby.

For every one that partaketh of milk is without experience of the word of righteousness; for he is a babe.

for every one who is partaking of milk `is' unskilled in the word of righteousness -- for he is an infant,

For everyone who lives on milk is still an infant, inexperienced in the message of righteousness.
