Genesis 16:10

And the angel of the Lord said unto her
The same as before, who, by what follows, appears to be Jehovah himself:

I will multiply thy seed exceedingly;
not that she should have many children herself, for that she had more than this one she now went with, is not certain; but that that seed she had conceived should be exceedingly multiplied, and he should have a numerous posterity, as he had twelve princes sprung from him, the heads of Arab nations:

that it shall not be numbered for multitude;
such the Turks are at this day, supposed to be the seed of Ishmael, Hagar's son.
