John Gill Commentary Acts 11:30

"which also they did, sending it to the elders by the hand of Barnabas and Saul." — Acts 11:30 (ASV)

Which they also did
They not only determined, but they put their resolutions into execution, and acted according to a rule which the apostle recommends, (2 Corinthians 8:11) (9:7)

and sent it to the elders ;
to the apostles; for though there were deacons there, yet they chose to send it to them, that they might put it into proper hands to distribute to the necessitous: and this collection they sent

by the hands of Saul and Barnabas ;
of this journey to Jerusalem, Paul makes no mention in (Galatians 1:17–19Galatians 1:21) (2:1) .
