Hebrews 10:36; Exodus 32:13

36 For yyou have need of endurance, so that zwhen you have done the will of God you may areceive what is promised.

13 Remember Abraham, Isaac, and Israel, your servants, to whom you pswore by your own self, and said to them, qI will multiply your offspring as the stars of heaven, and all this land that I have promised I will give to your offspring, and they shall inherit it forever.
