Rashi on Genesis 24:10/רש"י על בראשית כ״ד:י׳

1מגמלי אדניו OF HIS MASTER’S CAMELS — These were distinguished from other camels by going out muzzled to avoid robbery — i.e. that they should not graze in other peoples’ fields (Genesis Rabbah 59:11).

2וכל טוב אדניו בידו AND ALL THE GOODS OF HIS MASTER WERE IN HIS HAND — He wrote a deed of gift of all his possessions in favour of Isaac so that they would be eager to send him their daughter (Genesis Rabbah 59:11).

3ארם נהרים MESOPOTAMIA (literally, ARAM OF THE TWO RIVERS) — it was situated between the two rivers, Euphrates and Tigris.
