Halakhah sa Josue 9:27: Shulchan Arukh, Yoreh De'ah

If many poor seek help and there is not enough money in the treasury to help them all, a priest is given preference before a Levite; a Levite before an ordinary Israelite; an Israelite before a Halal;²The issue of a marriage forbidden to priests. See Levit. 21 : 7, 14. a Halal before a child of unknown fatherhood; such a one before a foundling; a foundling before a bastard; a bastard before a Nathin;³A descendant of the Gibeonites. Joshua 9:27; Zebahim 78b. (A treatise of the Talmud.) a Nathin before a proselyte; a proselyte before an emancipated slave. This applies only in case they are equal in learning. But between a bastard a scholar and a high priest an ignoramus, the scholarly bastard is given the preference; and so whosoever is greater in learning is preferred. However, if the father or teacher of the charity distributor is among the poor seeking aid, the teacher, or the father (provided he too is a scholar) is given the preference, even if there is a far greater scholar among them.
