The Righteous Man From The East

Isaiah 41
2 Who raised up the righteous man from the east, called him to his foot, gave the nations before him, and made him rule over kings?

So, who is the righteous man from the east?

Jamieson Faussett Brown
Cyrus; as Isa 44:28; 45:1-4, 13; 46:11, "from the East," prove. Called "righteous," not so much on account of his own equity [Herodotus, 3.89], as because he fulfilled God's righteous will in restoring the Jews from their unjust captivity.

John Gill Exposition Of The Bible
The Targum interprets this of Abraham; and so the Talmud; and this way go most Jewish and Christian commentators, and to him the characters agree; he was a righteous man, believed in Christ for righteousness, had the righteousness of faith when circumcised, did justice, and wrought righteousness himself, and required his children and servants to do the same, Genesis 15:6.

Matthew Henry Concise
Can any heathen god raise up one in righteousness, make what use of him he pleases, and make him victorious over the nations? The Lord did so with Abraham, or rather, he would do so with Cyrus.

There is no doubt that the righteous man, who may be Abraham or may be Cyrus, is a type for Jesus.

And who raised up the righteous man from the east?

Isaiah 41
4 .... I the LORD, the first, and with the last; I am he.

And so, the identity of the righteous man may not be that important. What is important is God's sovereignty in the affairs of man.
