We are fools ... in dishonor

Paul uses irony to shame the Corinthians so they will think about what he is saying. (See: rc://en/ta/man/translate/figs-irony)

You are held in honor

"People treat you Corinthians as though you are important people"

"people shame us apostles"

"Until now" or "Up to now"

This refers to hitting with the hand, not with whips or clubs. This can be stated in active form. AT: "people beat us" (See: rc://en/ta/man/translate/figs-activepassive)

Paul means that they had places to stay, but they had to move around from place to place. They had no fixed home.
