And when the Lord thy God shall deliver them before thee
Into their hands:
thou shalt smite them, and utterly destroy them;
men, women, and children; which was ordered not merely to make way and room for the people of Israel to inherit their land, but as a punishment for capital crimes they had been guilty of, such as idolatry, incest, murder wherefore though they were reprieved for a while for Israel's sake, till their time was come to possess the land, they were at length righteously punished; which observed, abates the seeming severity exercised upon them:
thou shalt make no covenant with them;
to dwell in their cities and houses, and enjoy their lands and estates, on any condition whatever; and though they did make a league with the Gibeonites, that was obtained by fraud, they pretending not to be of the land of Canaan, but to come from a very distant country:
nor show mercy unto them;
by sparing their lives, bestowing any favours upon them, or giving them any help and assistance when in distress: the Jews extend this to all other Heathen nations besides these seven; wherefore, if an Israelite, as Maimonides F26 says, should see a Gentile perishing, or plunged into a river, he may not take him out, nor administer medicine to a sick person. Hence Juvenal F1 the poet upbraids them with their unkindness and incivility; and says that Moses delivered it as a Jewish law, in a secret volume of his, perhaps referring to this book of Deuteronomy, that the Jews might not direct a poor traveller in his way unless he was one of their religion, nor one athirst to a fountain of water; and which led Tacitus F2, the Heathen historian, to make this remark upon them, that they entertained an hostile hatred against all other people.
