“And it came to pass after the death of Abraham, that God blessed his son Isaac; and Isaac dwelt by the well Lahairoi.”
King James Version (KJV)
25:11 And God blessed Isaac - The blessing of Abraham did not die with him, but survived to all the children of the promise. But Moses presently digresseth from the story of Isaac, to give a short account of Ishmael, for as much as he also was a son of Abraham; and God had made some promises concerning him, which it was requisite we should know the accomplishment of. He had twelve sons, twelve princes they are called, #Ge 25:16|, heads of families, which, in process of time, became nations, numerous and very considerable. They peopled a very large continent that lay between Egypt and Assyria, called Arabia. The names of his twelve sons are recorded: Midian and Kedar we oft read of in scripture. And his posterity had not only tents in the fields wherein they grew rich in times of peace, but they had towns and castles, #Ge 25:16|, where in they fortified themselves in time of war. Their number and strength was the fruit of the promise made to Hagar concerning Ishmael, #Ge 16:10|. and to Abraham, #Ge 17:20 21:13|.
