Man goeth forth - Man is now seen to go forth from his dwelling, and he appears on the stage to perform his daily toil, until evening comes, and then again he gives way for the beasts of night. Thus the scene is ever varying - showing how full of animated existence the earth is; how varied are the occupations of its different inhabitants; and how the varieties of being are adapted to its own varied condition in the alternations of day and night.

(m) Man goeth forth unto his work and to his labour until the evening.
(m) That is, when the day springs for the light is as it were a shield to defend man against the tyranny and fierceness of beasts.

Man goeth forth to his work,.... Having taken sleep in the night, being comfortably refreshed, and his strength recruited; he rises with the rising sun, and goes forth cheerfully and with intrepidity to his work in the field, or elsewhere, the beasts being fled and gone.
And to his labour until the evening; to till the ground, and do other services and labour, either of the head or hand; for man is born and designed for labour, and not for sloth and idleness: in his innocent state he was set to dress the garden and keep it; and, after the fall, his doom was to get his bread by the sweat of his brow; and he is to work while the day lasts, till the evening and night come on, when he betakes himself to sleep and rest again. So the believer, though the work of redemption and salvation is wrought for him, and the work of grace is wrought in him, each by another hand; yet he has work enough to do, which he is created for, and under obligation to perform; and in which he is to continue steadfast and immovable, while the day of life lasts, till the night of death comes, and no man can work; and then he rests from his labours, and his works follow him.
