Matthew Poole and continuators on 2 Corinthians 1:14

14 As also you have acknowledged us in part, that we are your rejoicing, even as ye also are ours in the day of the Lord Jesus .

In part, may either refer to persons, or things; part of you have so owned and acknowledged us, though others of you have abused us. Or you have in part, or at some times, owned us, that you had cause to bless God for us, and to rejoyce, that God ever sent us to preach the Gospel amongst you. And as some have owned us as their joy, or all of you have at some times acknowledged us as such; so you are also our rejoycing; we rejoyce that God hath made our labour successful to your Souls, and I trust in the day when the Lord Jesus shall come to judge the World, you shall be more our rejoycing.
