Ezekiel 33:24

Abraham was one— "If Abraham, being only a single person, had the whole country of Judaea given him, there is much greater reason to conclude, that God will preserve the possession of it to us, who are a numerous part of Abraham's posterity." These men speak after the vain manner of the Jews, who fondly presume that they have a right to all the promises made to Abraham, without considering the vast difference which was between them and Abraham, both in faith and practice. The appellation of one is given to that patriarch in other places of Scripture, because he was singled out from the rest of his family, to be the original or head of the Jewish nation.
