Here is nothing in this verse which needeth any explication, unless any should ask how it could be cold weather at that time of the year, (about April 14), especially in a country where it now was the time of harvest? Which may easily be resolved. It was now about three of the clock in the morning, and we know that in summer (the spring especially) nights are cold; besides that in those countries that are more equinoctial, the nights are longer, and consequently colder towards the morning, as the air hath had more time to cool.
