And Mishma, and Dumah, and Massa. Of Mishma and Massa, and of their posterity, there is not anything said elsewhere, unless the Masani, Ptolemy places near Arabia Felix, came from Massa. Dumah seems to be the same Isaiah speaks of in Ge 21:11; and in Arabia Deserta, where some of Ishmael's posterity settled, is a place called Dumaetha, by Ptolemy , which perhaps had its name from this son of his.
The Targum of Jonathan translates these three names,"hearing, silence, and patience;''which the Jews use as a proverb, when they would signify that there are some things to be heard and not spoken of, and to be patiently borne.
If Ishmael had in view to teach such lessons by the names he gave his children, he will seem to be a better man than he is usually thought to be. Georaph. l. 16. p. 528. 534. 536.
