'Ritualistic' in the Bible

"You are not to cut your hair in ritualistic patterns on your head or deface the edges of your beard.

"They are not to cut their hair in ritualistic patterns on their heads, deface the edges of their beards, or make incisions in their flesh.

and may be found in Him [believing and relying on Him], not having any righteousness of my own derived from [my obedience to] the Law and its rituals, but [possessing] that [genuine righteousness] which comes through faith in Christ, the righteousness which comes from God on the basis of faith.

Do not be carried away by diverse and strange teachings; for it is good for the heart to be established and strengthened by grace and not by foods [rules of diet and ritualistic meals], which bring no benefit or spiritual growth to those who observe them.
