Commemorated on October 9
The Righteous Forefather Abraham lived around 2000 B.C. His story is found in the Book of Genesis, Chapters 12-25.
God told Abraham that all the nations of the earth would be blessed in his seed (Genesis 22:18), and ordered him to leave his home and his relatives and go to Canaan, the country between the Mediterranean and Jordan. Because God gave this land to Abraham and his posterity (Genesis 12:7), it became known as "the Promised Land."
Abraham and Lot are also commemorated with Christ's ancestors according to the flesh on the Sunday of the Holy Forefathers (between December 11 and 17). SOURCE:
