9 October, Old Testament
The Lord called the Patriarch Abraham (first known as Abram) to become the father of a great nation (Genesis 12). At age 75, in obedience to God’s command, he, his wife Sarai (later Sarah), and his nephew Lot moved southwest from the town of Haran to the land of Canaan. There, the Lord cut a covenant with Abram (Genesis 15), promising the land of Canaan to his descendants. In Genesis 17:1-16, the Lord established circumcision as a sign of His covenant people while also renaming Abram as Abraham and Sarai as Sarah.
