from Andy Blackhall  – “House and riches are the inheritance of fathers” (Proverbs 19:14)

A.(14) Now for the third time I am ready to come to you.  And I will not be burdensome(a) to you;

B) for I do not seek yours, but you.

C) For the children ought not to lay up for the parents, but the parents for the children.

B’.(15) And I will very gladly spend and be spent for your souls; though the more abundantly I love you, the less I am loved.

A’.(16)  But be that as it may, I did not burden(b) you …
(a) narkaō (to be numb); to grow utterly torpid, that is, (by implication) slothful: – be burdensome (chargeable).
(b) katabareo to impose upon: – burden.
