God called the light day, and the darkness he called night— He gave them names as Lord of both, for the day is his, the night also is his. He is the Lord of time, and will be so till day and night shall come to an end, and the stream of time be swallowed up in the ocean of eternity. Let us then acknowledge him in the constant succession of day and night, and consecrate both to his honour, by working for him every day, and resting in him every night, and meditating in his law day and night.
Some have observed that the names here given to the two grand divisions of the day, are proofs of the expressiveness of the Hebrew language; יום jom, the day, expressing the tumult and business which attends it: and לילה lilah, the night, being derived from a word signifying the howling and yelling of the wild beasts, which then appear.
The evening and the morning— It is acknowledged by all, that each of these is put by a synecdoche for one half of the natural day. The darkness of the evening, or night, was before the light of the morning: it served as a foil to it, to set it off, and make it shine the brighter. It was on the ground of this and similar passages, that the Jews began both their common and sacred days with the evening. But this was not only the first day of the world, but the first day of the week. I observe it to the honour of that day, because the new world began likewise on the first day of the week in the Resurrection of Christ, as the Light of the world, early in the morning. In him the day-spring from on high hath visited the world; and happy are we if that day-star arise in our hearts.
