By faith, even Sarah herself received power to conceive, and she bore a child when she was past age, since she counted him faithful who had promised.
The woman conceived, and bore a son at that season, when the time came round, as Elisha had said to her.
Behold, Elisheva, your relative, also has conceived a son in her old age; and this is the sixth month with her who was called barren.
That is, it is not the children of the flesh who are children of God, but the children of the promise are counted as a seed.
However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise.
let us hold fast the confession of our hope without wavering; for he who promised is faithful.
