Deuteronomy 23:15 - Coke's Commentary on the Holy Bible

Ver. 15. Thou shalt not deliver unto his master the servant, &c.— i.e. A foreign servant, says Houbigant, not one of the Jewish nation; for it is not added, the servant of thy brother, or of thy neighbour: besides, Moses addresses the whole nation, as appears from the words, in one of thy gates [or cities:] so that there is little doubt, that the meaning of the law is, to appoint an asylum for foreign servants; either because the neighbouring nations would not restore the Israelitish servants who should fly to them, or because it concerned not the Israelites to judge those who were without.
