Deuteronomy 23:2

A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD.

Ver. 2. A bastard shall not enter.] Lest the reproach of his birth render him contemptible, or less courageous; a lest some son of Belial set upon him, as Saul did upon his son Jonathan, and say, "Thou son of the perverse rebellious woman." So of the base and beastly woman, "Do not I know that thou hast done this to the confusion of thy mother's nakedness?" 1Sa 20:30 The mutinous Janizaries called their Emperor Bajizet II, drunkard, beast, rascal, bastard, bengi, that is, bachelor, or scholar; and told him, moreover, that they would teach him to use his great place and calling with more sobriety and discretion. b The English slighted and scorned their William the Conqueror, because a bastard; in spite also to whom, and disgrace to his mother Arlet, they called all whores harlots. The Jews at this day, amongst other opprobrious words, wherewith they spitefully load us, call all Christians Mamzer Gel, that is, heathen bastards. Our Saviour, upon better grounds, called them long since, a bastardly brood. Mat 12:39 And their own prophet Isaiah did the same thing long before, Isa 57:3-4 and that, for their profane scoffing at the truth and the professors thereof. Yet who so forward as they, to say, "We are not born of fornication," no bastards? Joh 8:41

a Utpote qui nati sunt ex prostibulo, plane incerto patre, sed certissima infamia.
