Albert Barnes Commentary John 2:23

"Now when he was in Jerusalem at the passover, during the feast, many believed on his name, beholding his signs which he did." — John 2:23 (ASV)

Feast-day. Feast. During the celebration of the Passover, which continued eight days.

Miracles which he did. These miracles are not particularly recorded. Jesus took occasion to work miracles, and to preach at that time, for a great multitude were present from all parts of Judea. It was a favourable opportunity for making known his doctrines and showing the evidence that he was the Christ, and he embraced it. We should always seek and embrace opportunities of doing good, and we should not be deterred, but rather excited, by the multitude around us to make known our real sentiments on the subject of religion.
