'It is I' in the Bible

Did you undergo such a number of things to no purpose? if it is in fact to no purpose.

Because it is in the Writings, that Abraham had two sons, one by the servant-woman, and one by the free woman.

For it is in the Writings, You who have never given birth, be glad; give cries of joy, you who have had no birth-pains; for the children of her who has been given up by her husband are more than those of the woman who has a husband.
