Which [is] as a bridegroom coming out of his chamber, [and] rejoiceth as a strong man to run a race.
Ver. 5. Which is as a bridegroom coming out of his chamber] sc. After long expectation, with a great, deal of pomp and gaiety; such is the sun rasing, when he first showeth himself above our horizon. Kimchi addeth, that as the bride groom when he is abroad hasteneth home to his bride, so doth the sun to his descent, anhelat ad occasum, Ecclesiastes 1:5 .
And rejoiceth as a strong man (or champion) to run a race] Readily running, and effectually affecting all things with his heat. The Persian angari, or posts, the ostrich, the wild ass, the bustard, the dromedary, the eagle, is nothing so swift as the sun. Bellarmine saith (De Ascens. Mentis in Demn), that he runneth in the eighth part of an hour seven thousand miles. This dumb creature gives check to our dulness; as Balaam's ass also did to that prophet's madness.
