Rabbi Jonathan says, "Where do we learn that no present is to be made to an ignorant priest?" In 2 Chron. xxxi. 4, for there it is said Hezekiah "commanded that all the people that dwelt in Jerusalem should give a portion to the priests and to the Levites, that they might be strong in the law of the Lord." He who firmly lays hold of the law has a claim to a portion, otherwise he has none.
Chullin, fol. 130, col. 2.
The aged, if ignorant, grow weaker in intellect the older they become in years, for it is written (Job xii. 20), "He removeth away the speech of the trusty, and taketh away the understanding of the aged." But it is not so with them that are old in the study of the law, for the older they grow the more thoughtful they become, and the wiser, as it is said (Job xii. 12), "With the ancient is wisdom, and in length of days understanding."
Kinnin, chap. 3.
The salutation of the ignorant should be responded to quietly, and with a reluctant nod of the head.
Taanith, fol. 14, col. 2.
No calamities ever befall the world except such as are brought on by the ignorant.
Bava Bathra, fol. 8, col. 1.
Rav Hunna's widow once appeared before Rav Nachman as plaintiff in a lawsuit. "What shall I do?" he said. "If I rise before her (to honor her as the widow of a Rabbi), the defendant, who is an amhaaretz, will feel uneasy; and if I don't rise I shall break the rule which ordains that the wife of an associate is to be treated as an associate." So he said to his servant, "Loose a young goose over my head, then I'll get up."
