Albert Barnes on John 12:21

Bethsaida of Galilee. Jn 1:44.

Would see Jesus. It is probable that the word see, here, implies also a desire to converse with him, or to hear his doctrine about the nature of his kingdom. They had seen or heard of his triumphal entry into Jerusalem, and, either by curiosity or a desire to be instructed, they came and interceded with his disciples that they might be permitted to see him. In this there was nothing wrong. Christ made the curiosity of Zaccheus the means of his conversion, Lk 19:1-9. If we wish to find the Saviour, we must seek for him and take the proper means.

(u) "to Philip" Jn 1:44
