Neither shall thy name be any more called Abram,.... Which signifies an "high father", which name he bore for many years before he was the father of anyone:
but thy name shall be Abraham: with all addition of the letter ה inserted into it, and makes the last syllable two, "raham": which word in the Arabic language, as Hottinger g observes, signifies "numerous" h; so that with this addition his name Abraham may be interpreted, the father of a numerous offspring; and with this agrees the reason of it, as follows:
for a father of many nations have I made thee; not that he was so already in fact, but in the purpose and promise of God, Romans 4:17; Abraham has not only been the father of many nations, in a literal sense, as before observed, but in a mystical sense, of the whole world; that is, of all in it that believe, whether Jews or Gentiles; and so the Rabbins i interpret it: at first, they say, he was the father of Aram, and therefore his name was called Abram, but now he is the father of the whole world, and therefore called Abraham; and so Maimonides k himself says, quoting this passage,
"behold he is the father of the whole world, who are gathered under the wings of the Shechinah.''
