Hebrews 11:11-12

11By faith even Sarah herself received the ability to conceive [a child], even [when she was long] past the normal age for it, because she considered Him who had given her the promise to be reliable and true [to His word].

12So from one man, though he was [physically] as good as dead, were born as many descendants as the stars of heaven in number, and innumerable as the sand on the seashore.
