He made the one and the other, and divided the one from the other; and can make them longer or shorter, clear or cloudy, as he pleases: and the day of prosperity and night of adversity are at his disposal; all the times of his people and of his church are in his hands; sometimes it is a night of darkness, deadness, sleepiness, and security, as it now is; ere long there will be no more night, but bright day; the light of the moon will be as the light of the sun, and the light of the sun will be seven fold as the light of seven days; and this is to be expected from him whose is the day and the night also, Re 21:25.
Jarchi interprets the day, of the redemption of Israel; and the night, of distresses and afflictions:thou hast prepared the light and the sun; first the light, and then the sun; for the light was before the sun; or the luminary, even the sun.
