And when you release him, do not send him away empty-handed.
13. 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.
God's people must not be held in perpetual slavery; thus are His spiritual Israel called unto liberty. When released, masters must furnish them with stock to begin again, for they leave with nothing of their own. A servant who chooses to stay for life gets reputation among some as quiet and contented, among others as one without due sense of freedom's honor.

Commenting on Deuteronomy 15:12-18
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.
