NOTES for Isa 11:4
All the latest prophets, including Isaiah of Jerusalem, looked at the Messiah as a righteous judge. But what is in substance a righteous judgment? If this question was given to one of the earlier prophets - the spiritual predecessors of Isaiah, each of them would answer: it is the judgment made according to the Torah, the law given by God, only by which the people of God has to live. But can we consider such a judgment as God's judgment in all the proper sense of the word? Not fortuitously In the Jewish text of the biblical books notions "justice" and "righteousness" indicate the same word.
Only a righteous man can be a fair judge. But where to find such a judge then? Where to find the blameless righteous, not dominated by sin? It is not fortuitously if all true righteous men and real judges considered only God as the Divine Judge. Only He can judge man; the earthly judge can only judge concrete acts. But what, if the man carries accomplishes not his judgment, even if it is in full conformity with the law given by God, but rather God's judgment?
Can God use a man for His judgment? And who should be such a person? This was revealed to Isaiah: such a Person can be only the One sent by God - the Messiah, whose life will fully be, without remainder, belongs not to Himself, as a Man, but to God, Who sent Him into the world. So this Man sees the accused in the same way as God sees. And that is why the decision of the Messiah becomes an act of God's judgment - the fair judgment of a righteous Judge.
