John Calvin Commentary John 1:39

"He saith unto them, Come, and ye shall see. They came therefore and saw where he abode; and they abode with him that day: it was about the tenth hour." — John 1:39 (ASV)

It was about the tenth hour; that is, the evening was approaching, for it was not more than two hours until 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.
