2 Corinthians 11:9
And when I was present with you, and wanted, I was chargeable to no man: for that which was lacking to me the brethren which came from Macedonia supplied: and in all [things] I have kept myself from being burdensome unto you, and [so] will I keep [myself].
Note 14 at 2Co 11:9: When Paul was with the Corinthians and was in want (i.e., he lacked or needed something), he was chargeable to no one. The Greek word for "chargeable" in this verse is "KATANARKAO," used only here and in 2Co 12:13-14, and it carries the idea of a heavy load that is burdensome. His financial responsibilities were met by his own hands and also by the Macedonian churches. By not being chargeable to the Corinthians, Paul hoped to teach by example the truth of personal responsibility (2Th 3:7-10) and his deep love for the Corinthians (2Co 6:11).
Note 15 at 2Co 11:9: This is a very clear reference to the fact that Paul did receive offerings; he just didn't receive offerings from the Corinthians (see note 3 at 1Co 9:4 and note 5 at 1Co 9:6) and the Thessalonians (1Th 2:9). Later in this same letter (2Co 12:13), Paul asked the Corinthians to forgive him for not letting them help him financially. He even said he was wrong for doing so. This was probably sarcastic, but it nonetheless shows that giving to those who minister to them has great benefit for the givers.
Note 16 at 2Co 11:9: Although Paul was entitled to receive support from the Corinthians, he had not done so, and here, he was saying that he would not do so.
