15 So then, brethren, (A)stand firm and (B)hold to the traditions which you were taught, whether (C)by word of mouth or (D)by letter [a]from us.
19 keeping (A)faith and a good conscience, which some have rejected and suffered shipwreck in regard to [a](B)their faith.
13 [a](A)Retain the (B)standard of (C)sound words (D)which you have heard from me, in the (E)faith and love which are in (F)Christ Jesus.
