No offense, but I'm also not very impressed with your hermeneutics.

All you did was copy paste four words from a Greek dictionary!
I could write out a proper exegesis of the text, but so far I think that approach would be a waste of my time.
The key to understanding 2Cor 8:9 is context, but it's the context of the language, as well as the subject.
Paul sets the tone for 2Cor 8:9 in this earlier passage:
4 but as servants of God we commend ourselves in every way: by great endurance, in afflictions, hardships, calamities,
5 beatings, imprisonments, riots, labors, sleepless nights, hunger;
6 by purity, knowledge, patience, kindness, the Holy Spirit, genuine love;
7 by truthful speech, and the power of God; with the weapons of righteousness for the right hand and for the left;
8 through honor and dishonor, through slander and praise. We are treated as impostors, and yet are true;
9 as unknown, and yet well known; as dying, and behold, we live; as punished, and yet not killed;
10 as sorrowful, yet always rejoicing; as poor, yet making many rich; as having nothing, yet possessing everything.
2 Corinthians 6:4-10 ESV
For Paul, and us, to be consistent we can't assume that Paul is contradicting himself.
4 but as servants of God we commend ourselves in every way: by great endurance, in afflictions, hardships, calamities,
...
10 as sorrowful, yet always rejoicing; as poor, yet making many rich; as having nothing, yet possessing everything.
2 Corinthians 6:4-10 ESV
our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that you by his poverty might become rich.
2 Corinthians 8:9b ESV
The only intellectually honest and consistent way to interpret these two passages is that the disciples were physically poor but making people spiritually rich (2Cor 6:4-10), and that they followed Christ's example in that He became physically poor to make people spiritually rich (2Cor 8:9).
How do you interpret 2Cor 6:4-10?
peace,
Simon
