Romans 4 v 19



Romans 4:19
And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara's womb:


Verses 19-21 restate in specific details the first part of verse 18 about Abraham’s hope. Abraham without weakening in his faith . . . faced the fact (lit., “considered carefully”) that his body was as good as dead (some Gr. mss. add the word “already”), a reference to the patriarch’s advanced age (Gen. 17:17; 21:5). Abraham also considered carefully that Sarah’s womb was also dead. She was unable to conceive a child, as had been demonstrated through their life together (cf. Gen. 16:1-2; 18:11) and as was certainly true for her at age 90 (Gen. 17:17).
