'Superior' in the Bible

"A disciple is not superior to his teacher, nor a slave superior to his master.

A disciple is not superior to [his] teacher, but everyone, [when he] is fully trained, will be like his teacher.

and know his will and approve the things that are superior, [because you] are instructed by the law,

so that you may approve what is superior, in order that you may be sincere and blameless in the day of Christ,
