Reading from the Synaxarion:

11th Sunday of Luke

On the Sunday that occurs on or immediately after the eleventh of this month, we commemorate Christ's forefathers according to the flesh, both those that came before the Law, and those that lived after the giving of the Law.

Special commemoration is made of the Patriarch Abraham, to whom the promise was first given, when God said to him, "In thy seed shall all the nations of the earth be blessed" (Gen. 22:18).

This promise was given some two thousand years before Christ, when Abraham was seventy-five years of age. God called him and commanded him to forsake his country, parents, and kinsmen, and to depart to the land of the Canaanites. When he arrived there, God told him, "I will give this land to thy seed" (Gen. 12:7); for this cause, that land was called the "Promised Land," which later became the country of the Hebrew people, and which is also called Palestine by the historians. There, after the passage of twenty-four years, Abraham received God's law concerning circumcision. In the one hundredth year of his life, when Sarah was in her ninetieth year, they became the parents of Isaac. Having lived 175 years altogether, he reposed in peace, a venerable elder full of days.
