In the future God will assign to each righteous man three hundred and ten worlds as an inheritance; for it is said (Prov. viii. 21), “That I may cause those that love me to inherit substance, and I will fill their treasures.”  By Gematria equals three hundred and ten.

An old woman once complained before Rav Nachman that the Head of the Captivity and certain Rabbis with him were enjoying themselves in her booth, which they had surreptitiously taken possession of and would not surrender, but Rav Nachman gave no heed to her remonstrance.  Then she raised her voice and cried aloud, “A woman whose father had three hundred and eighteen slaves is now pleading before you, and you paying no heed to her!” Upon which Rav Nachman turned to his associates and said, “She is a bawling woman, but she has no right to claim the booth, only the value of its timber.”

Elijah the Tishbite once said to Rav Yehudah, the brother of Rav Salla the Holy, “You ask why the Messiah does not come, even though it is just now the Day of Atonement.”  “And what,” asked the Rabbi, “does the Holy One—­blessed be He!—­say to that?” “He says, ‘Sin lieth at the door’” (Gen. iv. 7).  “And what has Satan to say?” “He has no permission to accuse any one on the Day of Atonement.”  “How do we know this?” Ramma bar Chamma replied, “Satan by Gematria equals three hundred and sixty-four, therefore on that number of days only has he permission to accuse; but on the Day of Atonement (i.e., the 365th day) he cannot accuse.”

Rav Yitzchak said, “What is the meaning of that which is written (Ps. cxl. 8), ’Grant not, O Lord, the desires of the wicked; further not his wicked device, lest they exalt themselves.  Selah?’” It is the prayer of Jacob to the Lord of the universe that He would not grant to Esau, “the wicked, the desires of his heart.”  “Further not his wicked device,” this refers to Germamia of Edom (i.e., Rome), for if they (the Romans) were suffered to go forward they would destroy the whole world!  Rav Chama bar Chanena said, “There are three hundred crowned heads in Germamia of Edom, and there are three hundred and sixty-five dukes in Babylon.  These encounter each other daily, and one of them commits murder, and they strive to set up a king.”
