These all, both beasts and fishes, wait upon thee, expect supplies only from thy providence; which is said of them figuratively, and with an allusion to the manner of tame beasts and fowls, which commonly look after and wait upon those persons who bring their food to them. In due season; when it is necessary or convenient for them; by which expression he intimates the moderation of the beasts in their desires of food, and tacitly reproves the intemperance of men who feed themselves in season and out of season.
