Romans 4:18-22

Against tikvah (hope), in tikvah “he believed,” in order that he might become AV HAMON GOYIM (father of many nations) in accordance with what had been said, So shall your ZERA (seed) be. Without weakening in emunah (in personal faith, bitachon, trust) he contemplated his own body, now as good as dead vi-bahlt (since) he was about one hundred years old, and also the deadness of Sarahʼs womb. He did not, in disbelief, doubt the havtachah of HASHEM (the promise of G-d), but was strengthened in emunah (faith), giving kavod (glory) to HASHEM, Being fully convinced that what HASHEM had promised He also was able to do. Therefore, V'YACHSHEVEHHA LO TZEDAKAH (it was credited to him for righteousness).
