A.T. Robertson Commentary 1 Corinthians 16:4

"and if it be meet for me to go also, they shall go with me." — 1 Corinthians 16:4 (ASV)

And if it be meet for me to go also (εαν δε αξιον η του καμε πορευεσθα). "If the collection be worthy of the going as to me also." Condition of third class (εαν--η) and the articular infinitive in the genitive (του) after αξιον. The accusative of general reference (καμε, me also) with the infinitive. So the awkward phrase clears up.
