Abraham the Righteous & his nephew Lot

Reading from the Synaxarion:

The holy Patriarch Abraham, born a pagan, ten generations after Noah,
when the knowledge of God had perished from among men, became the
beginning of God's dispensation for the universal renewal and salvation of
man. He was called out of his country--the land of the Chaldees, that
is, Mesopotamia--to the land of Canaan, and received the promise that
through his seed all the nations of the earth should be blessed; through
his singular faith in the promises of God, he was justified before
the giving of the Law and the coming of Grace; through his
willingness to sacrifice Isaac, he portrayed the love wherewith God loved the
world in sacrificing His only-begotten Son. The greatness of Abraham,
and the trials that he and his righteous nephew Lot underwent, are
set forth in the Book of Genesis in the Old Testament, chapters
twelve through twenty-five. See also the Sunday of the Holy
Forefathers, December 11-17.

Apolytikion in the Plagal of the First Tone
In the night universal of ignorance towards God, and in that
starless, profound gloom bereft of heavenly light, thou, O Abraham, wast
kindled in the firmament, burning with bright far-shining faith in the
Everlasting Light, Who shone forth to us from thy seed. Do thou entreat Him
with fervour, that He enlighten us and save our souls.

Kontakion in the Second Tone
The servant wast thou, a mortal fashioned from the earth; thy master
was God, creation's Lord and Fashioner; yet, well-pleased to glorify
thy celestial greatness, the Lord of all called Himself the God of
Abraham. Procure for us mercies from thy merciful Lord.
