(1:7) God said to us at Horeb, “Turn around and head toward the Amorite highland and all its neighboring territory, in the Aravah, the hill country, the lowlands, the Negev, the seashore, the Canaanite territory, as far as the great river, the Euphrates River.”
the great river, the Euphrates River Shimon b. Tarfon said: This is an example of the popular saying: Touch a person who is smeared with oil, and some of it will rub off on you (Rashi on Shevuot 47b, entry for kerav).
NOTE: The Euphrates is really the smallest of the four rivers listed in Genesis 2:14, but this verse calls it “the great river” because it is mentioned in connection with the Land of Israel; and anything connected with the Land of Israel is great.
(1:16) Moses said, “I then gave instructions to your judges, saying, 'Listen to every dispute among your brethren, and judge honestly between each man and his brother, especially when a proselyte is concerned.'”
