JMNT(i)
14 Look (or: Consider)! This third time I continue holding [myself] ready and prepared to come to (or: go toward) you folks – and I will not proceed in being "dead weight" (an encumbrance or burden), for I am not habitually seeking your "things" (your possessions), but to the contrary, you. For the children ought not to be habitually storing up and accumulating [material resources] for the parents, but rather, the parents [should do this] for the children.
15 So I myself most gladly shall spend (pay the expenses) – even be completely spent (exhausted; bankrupted) – over (on behalf of) your souls. Even if I am constantly loving you excessively, I am habitually being loved less. (or: And since I am continuously loving you more abundantly {or: too much}, am I being loved less?)
16 Yet, let it continue to be. I myself do not (or: did not) overburden or weigh you down. Nonetheless, being inherently ready to do anything and capable for every work, [you say that] I caught you, taking you by bait (as used for fish)!
