P’sachim, fol. 49, col. 2.

Rav Yehudah says it is good to eat the pulp of a pumpkin with beetroot as a remedy, also the essence of hemp seed in Babylonian broth; but it is not lawful to mention this in the presence of an illiterate man, because he might derive a benefit from the knowledge not meant for him.

Nedarim, fol. 49, col. 1.

No contribution or heave-offering should be given to an ignorant priest.

Sanhedrin, fol. 90, col. 2.

No boor can be pious, nor an ignorant man a saint.

Sleep in the morning, wine at mid-day, the idle talk of inexperienced youth, and attending the conventicles of the ignorant drive a man out of the world.

Ibid., chap. 3, mish. 16.

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.

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.”

Rav bar Sheravyah had a lawsuit with an amhaaretz before Rav Pappa, who bade him be seated, and also asked the other to sit down.  When the officer of the court raised the amhaaretz with a kick, the magistrate did not request him to be seated again.

Shevuoth, fol. 30, col. 2.

Six things are said respecting demons.  In three particulars they are like angels, and in three they resemble men.  They have wings like angels; like angels they fly from one end of the world to the other, and they know the future, as angels do, with this difference, that they learn by listening behind the veil what angels have revealed to them within.  In three respects they resemble men.  They eat and drink like men, they beget and increase like men, and like men they die.
