The following is a start at a map between Isaiah 51 and the book of Galatians.
13 Isaiah 51:1-2
1Listen to me, you who follow after righteousness, you who seek Yahvah; look to the mountain from which you were hewn, and to the hole of the pit from which you were dug.
2Look to Abraham your father, and to Sarah who conceived you; for he was alone, and I called him and blessed him and multiplied him.
51 Galatians 3:6-7
6just as Abraham believed God, and it was accounted to him for righteousness?
7Therefore you must know that those who trust in faith are the children of Abraham.
13 Isaiah 51:3-23
3For Yahvah will build Zion; he will build all her waste places; he will make her wilderness like Eden, and her desert like the garden of Yahvah; joy and gladness will be heard in the middle of her, thanksgiving and the voice of singing.
4Listen to me, people; and give ear to me, nations; for a law will go forth from me, and my justice is a light to the Gentiles.
5My righteousness is near; my salvation is gone forth and my arms will judge the peoples; the islands will wait for me and on my arm they will trust.
6Lift up your eyes to the skies, and also look on the land beneath; for the skies will vanish away like smoke, and the land will wear out like a garment, and they who live in it will perish in like manner; but my salvation will be forever, and my righteousness will not pass away.
7Listen to me, you who know righteousness, the people in whose heart is my law; do not fear the disgrace of men, nor be afraid of their revilings.
8For the moth will eat them up like wool and like a garment; but my righteousness will be forever and my salvation from generation to generation.
9Awake, awake, put on strength, arm of Yahvah; awake as in the ancient days, as in the generations of old. Surely it was you who decreed a severe sentence that slayed the dragon.
10It was you who dried up the sea, the waters of the great deep; that made the depths of the sea a way for the redeemed to pass over.
11Therefore the redeemed of Yahvah will return, and come with singing to Zion; and everlasting joy will be on their heads; they will obtain gladness and joy; and sorrow and sighing will flee away.
12I, even I, am he that comforts you says Yahvah; who are you, that you should be afraid of a man that will die, and of the son of man that dries up like grass;
13and you have forgotten Yahvah your Maker, who stretched forth the skies and laid the foundations of the land; and have been afraid continually every day because of the fury of the oppressor, who was ready to destroy? And now where is the fury of the oppressor?
14The oppressor hurried to destroy the mighty ones, but they will not die nor be destroyed, nor will their bread fail.
15For I am Yahvah your God who rebukes the sea, and its waves are calm; Yahvah of hosts is his name.
16And I have put my words in your mouth, and I have covered you in the shadow of my hand, because I stretched forth the skies and laid the foundations of the land and said to Zion, You are my people.
17Awake, awake, stand up, Jerusalem, because you have drunk at the hand of Yahvah the cup of his fury; you have drunk to the dregs of the cup of trembling, and drained it.
18There is no one to comfort her among all the sons whom she has borne; nor is there any of all the sons that she has brought up that takes her by the hand.
19These 2 things are come to you; who will be sorry for you? You will have plunder, destruction, famine, and sword; who will comfort you?
20Your sons have fainted, they lie at every street corner, they are faded like a wilted beet; they are full of the fury of Yahvah, the rebuke of your God.
21Now hear this, afflicted and drunk, but not with wine;
22your Master Yahvah, and your God, who pleads the cause of his people says: Look, I have taken out of your hand the cup of trembling, and you will not drink from the cup of my fury any longer;
23but I will put it into the hand of those who afflict you, who have said to your soul, Bow down that we may go over you; and you have made your people like the ground and like the street to those who passed by.
