'Concerning' in the Bible

wanting to be teachers of the law, [although they] do not understand either [the things] which they are saying or [the things] concerning which they are speaking confidently.

having faith and a good conscience, which some, [because they] have rejected [these], have suffered shipwreck concerning their faith,

he is conceited, understanding nothing, but having a morbid interest concerning controversies and disputes about words, from which come envy, strife, slanders, evil suspicions,

which some, [by] professing [it], have deviated concerning the faith. Grace [be] with you [all].
