Commenting on Genesis 22:20-24
And Chesed,.... From whom it is generally thought sprung the Chaldees, who are commonly called Chasdim; but mention is made of the Chaldees before this man was born, unless they are called so by anticipation; See Gill on Gen 10:22, and Hazo, and Pildash, and Jidlaph, and Bethuel; of these men and their posterity we hear no more, excepting: the last, for whose sake the rest are mentioned.
Huz - He is supposed to have peopled the land of Uz or Ausitis, in Arabia Deserta, the country of Job.
