John Calvin on John 1:39

39. It was about the tenth hour; that is, the evening was approaching, for it was not more than two hours till sunset. The day was at that time divided by them into twelve hours, which were longer in summer and shorter in winter. But from this circumstance we infer that those disciples were so eagerly desirous to hear Christ, and to gain a more intimate knowledge of him, that they gave themselves no concern about a night’s lodging. On the contrary, we are, for the most part, very unlike them, for we incessantly delay, because it is not convenient for us to follow Christ.

John 1:40-42

40. Andrew, Simon Peter’s brother, was one of those who heard John speak and followed him. 41. He first findeth his own brother Simon, and saith to him, We have found the Messiah, which is, being interpreted, the Christ. 42. He brought him therefore to Jesus; and Jesus, looking at him, said, Thou art Simon, the son of Jonah; thou shalt be called Cephas, which is, being interpreted, Peter.
