Genesis 13:16
And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, then shall thy seed also be numbered.
And I will make thy seed as the dust of the earth,.... An hyperbolical expression denoting the great multitude of Abram's posterity, as they were in the days of Solomon, and as they will be in the latter day; and especially as this may respect all the spiritual seed of Abram, Jews and Gentiles, and as they will be in the spiritual reign of Christ, see Hosea 1:10;
so that if a man can number the dust of the earth, then shall thy seed be numbered; but as it is impossible to do the one, so the other is not practicable, see Numbers 23:10.
