Matthew Henry on 1 Corinthians 4:17–end
Here, I. He tells them of his having sent Timothy to them, to bring them into remembrance of his ways in Christ, as he taught every where in every church (Co1 4:17) - to remind them of his ways in Christ, to refresh their memory as to his preaching and practice, what he taught, and how he lived among them.
