Albert Barnes on 2 Corinthians 9:1

For as touching the ministering to the saints. In regard to the collection that was to be taken up for the aid of the poor Christians in Judea. Rom 15:26, 1Cor 16:11, 2Cor 8.

It is superfluous, etc. It is needless to urge that matter on you, because I know that you acknowledge the obligation to do it, and have already purposed it.

For me to write to you. That is, to write more, or to write largely on the subject. It is unnecessary for me to urge arguments why it should be done; and all that is proper is to offer some suggestions in regard to the manner in which it shall be accomplished.
