John Gill 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 that I go also
If it should be convenient for me to go, or it should be thought proper and expedient that I should go; or, as the Syriac version renders it, "if this work should be worthy that I should go"; and the Arabic version, "if the thing should be worthy to go with me"; that is, their beneficence; if so large a collection should be made, that it will be worthy of an apostle to go along with it, hereby artfully pressing them to a good collection:

they shall go with me ;
that is, those brethren whom the church shall approve and send; for he would not go alone, nor propose it, to remove all suspicion of converting any money to his own use.
