Genesis 21:1-3 Wycliffe Bible (WYC)
21 Forsooth God visited Sarah, as he promised, and [ful]filled those things, that he spake.
2 And she conceived, and childed a son in her eld (age), in the time wherein God before-said to her. (And she conceived, and bare a son in her old age, at the time which God had spoken of before to her.)
3 And Abraham called the name of his son, whom Sarah childed to him, Isaac.
