'Concerning' in the Bible

willing to be teachers of law, not understanding either the things they say, nor concerning what they asseverate,

This command I entrust to you, Timothy, my son, in accordance with the prophecies previously made concerning you, that by them you fight the good fight,

Holding faith, and a good conscience; which some having put away concerning faith have made shipwreck:

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 professing have erred concerning the faith. Grace be with thee. Amen.
