John Calvin on John 13:29-30

29. Or that he should give something to the poor. It is plain enough from other passages how great was Christ’s poverty, and yet, out of the little that he had, he gave something to the poor, in order to lay down a rule for us; for the Apostles would not have conjectured that he had spoken about the poor, if it had not been their usual custom to relieve the poor

John 13:30-35

30. When, therefore, he had received the sop, he went immediately out; and it was night. 31. When, therefore, he was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him. 32. If God is glorified in him, God will also glorify him in himself, and will immediately glorify him. 33. Little children, but a little while am I yet with you. You shall seek me, and as I said to the Jews, that whither I go, you cannot come, so now I say to you. 34. A new commandment I give you, That you love one another; as I have loved you, that you also love one another. 35. By this will all men know that you are my disciples, if you have love one to another.
