Abraham is the father of the Israelites. It is with Abraham that God makes his covenant and promise.

Abraham is the name God gives to Abram when he makes his covenant with him.

Abram at God's command had left his home city of Ur of the Chaldees, in the Tigris-Euphrates basin. God promised Abram that he will make of his children, a great nation : greater than the sands of the sea-shore.

The apex of the window shows "A rose-red city-half as old as Time!" As if in the rosy-tinted dawn of history, there emerge the outlines of the City of Salem, later to become known as "Uru-Salem" or Jerusalem, the city of a beautiful name destined to be symbolised in prose and poetry as the City of God.

The figure of Abraham dominates the window. The "the father of many nations" is shown with the knife in hand which he took to slay his son Isaac, that he might offer him up for a burnt offering to the Lord (Gen. 22).

The section at the base of the window shows Abraham having on his return from battle been blessed by Melchizedec, (the King of Salem and Prince of the Most High God), presenting the King with a tenth (a tithe) of all the spoils of victory (Gen. 14 and Heb. 7).
