And when thou sendest him out free from thee. Here not only is the enfranchisement of slaves enjoined, but an exhortation to liberality is also added, viz., that they should not send away their slaves without their hire; for this is not a civil enactment for the purpose of extorting from the avaricious more than they were willing to give. The rule of Paul here applies: "Every man according as he purposeth in his heart, so let him give; not grudgingly or of necessity: for God loveth a cheerful giver." (2-Corinthians 9:7.) But, since the Hebrew slaves were brethren, God would not allow them to be placed in a worse condition than hirelings. That He commands them to be furnished out of the wine-press, and floor, and flock, does not mean that they were to be enriched, or that a large provision should be assigned to them, but He justly lays a constraint on the rich, whose varied abundance supplied them with the means of liberality; as if He would show them from whence they received their gratuitous gifts, which were at the same time a just compensation for the labors of their slaves.

Thou shalt not let him go away empty - Because during the time he served thee, he made no property for himself, having been always honest towards thee; and now when he leaves thee, he has nothing to begin the world with.

And when thou sendest him out free from thee,.... When he discharged him from his servitude, and made him a free man:
thou shall not let him go away empty; without anything to support himself, or to put himself in a way of business; he having in the time of his servitude worked entirely for his master, and so could not have got and saved anything for himself.

thou shalt not let him go away empty--A seasonable and wise provision for enabling a poor unfortunate to regain his original status in society, and the motive urged for his kindness and humanity to the Hebrew slave was the remembrance that the whole nation was once a degraded and persecuted band of helots in Egypt. Thus, kindness towards their slaves, unparalleled elsewhere in those days, was inculcated by the Mosaic law; and in all their conduct towards persons in that reduced condition, leniency and gentleness were enforced by an appeal which no Israelite could resist.
