Webster(i)
18 Who against hope believed with hope, that he should become the father of many nations; according to that which was spoken, So shall thy seed be.
19 And being not weak in faith, he considered not his own body now dead, when he was about a hundred years old, neither yet the deadness of Sarah's womb.
20 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
21 And being fully persuaded, that what he had promised, he was able also to perform.
