Genesis 25:14

Mishma, and Dumah, and Massa - Where the first and last of these settled is not known; but it is probable that Dumah gave his name to a place called Dumah in Arabia. See a prophecy concerning this place, Isaiah 21:11 ; (note), from which we find that it was in the vicinity of Mount Seir.

These three names have passed into a proverb among the Hebrews, because of their signification. משמע mishma signifies Hearing; דומה dumah , Silence; and משא massa , Patience. Hence, "Hear much, say little, and bear much," tantamount to the famous maxim of the Stoics, Ανεχου και απεχου , "Sustain and abstain," is supposed to be the spirit of the original words.
