And God will say to Abraham, It shall not be evil in thine eyes concerning the boy, and concerning thy maidservant; all which Sarah shall say to thee, hear to her voice; for in Isaak the seed shall be called to thee.
And God will say. Truly, Sarah thy wife, shall bring forth to thee a son, and shall call his name Isaak: and I set up my covenant with him for a lasting covenant, and to his seed after him.
