2 Corinthians 9:5

‘I thought it necessary therefore to entreat the brethren, that they would go before to you, and make up beforehand your previously promised bounty, that the same might be ready as a matter of bounty, and not of extortion (covetousness).'

So that was why he had felt it necessary to send these three men, ‘the brethren', to them in advance, so that they could ensure that the collection, which in their bounty they had previously promised, was gathered together and ready on a fully voluntary and willing basis as a genuine act of bounty, and not one that was revealed as given reluctantly in haste.

The final word may demonstrate his concern against forcing a gift from them (extortion) or refer to giving the impression of a grudging response (giving with a money-loving attitude). The mention of these men in this way also assumes a connection with the previous chapter.

We should note here how little pressure he puts on in order to persuade them to give. He refuses to use high pressure methods, while at the same time giving pause for thought. However, his eagerness for the success of his project is such that he decides to add further force to his previous persuasive arguments in chapter 8. So with this in mind he quotes what is possibly a well known proverb, (although there is actually no evidence elsewhere of such a proverb), in order to gently urge them towards being generous.
