Verse 6. -
And I will make thee exceeding fruitful, and I will make nations of thee, - a promise fulfilled in the Ishmaelites, the descendants of Keturah, the Edomites, and the Israelites -
and kings (e.g. David and Solomon)
shall come out of thee.
17:1-6 The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, a high father, to Abraham, the father of a multitude. All that the Christian world enjoys, it is indebted for to Abraham and his Seed.
And I will make thee exceeding fruitful,.... In children, for he had not only a son by Sarai, from whom sprung a numerous offspring, but he had six sons by Keturah, who became the heads of large nations:
and I will make nations of thee; as the nations of Israel and Judah, of the Midianites and Edomites, of the Arabs, Saracens, and Turks:
and kings shall come out of thee; as the twelve princes of Ishmael, the kings of Edom and Midian, of the Arabs, Saracens, and Turks, and of Israel and Judah, and especially, as observed by Grotius, and others, the King Messiah: to which may be added, in a mystical sense, all Christian kings and princes of the same faith with him; nay, all believers, who are all kings and priests unto God.
