Isaiah 53:11 "knowledge"

As I read Isaiah 53:11 in the KJV, I come across the word "knowledge". "By his (Christ's) knowledge shall my righteous servant (Christ) justify many." Christians are justified, reckoned "just" by what Christ did for them on the cross. We are not "just" because we have sinned, but we are reckoned "just" by God, because Jesus paid for our sin. 2 Corinthians says "For he hath made him to be sin for us, who "knew" no sin: In His omniscience Christ "knows" everything. Genesis 2:17 speaks of "the tree of the 'knowledge of good and evil,.." In Genesis 3:5 the serpent says "For God doth know that in the day ye eat thereof, then your eyes shall be opened and ye shall be as gods, knowing good and evil." In Genesis 3:22 it says "And the LORD God said, Behold, the man is become as one of us, to 'know' good and evil..." It is one thing to be holy, separate from sin (Hebrews 7:26) knowing sin through omniscience, and another to know sin through doing it or experiencing it. Which bring me to my original intent in sharing the word "knowledge" in Isa 53:11. Though Jesus never sinned, I believe He knew on the cross what it felt like to be a sinner, to be judged as a sinner. He took our place, we being sinners, so that he could take the penalty for our sin. I believe this was what he was dreading and sweating blood over in the Garden of Gethsemane, not the pain of nails in his body, or the whip upon his back, and other physical torture; but He, being purely holy, becoming, in the reckoning of God the Father, as the One guilty of every sin that would ever be committed. That is a lot of sin. Not just the sin of lying, but every lie that has ever been lied. For us, like trying to understand what thousands of lightyears are, this is incomprehensible. It is beyond our ability to comprehend (in other words). We simply understand that lightyears are a long ways away, and Jesus paid for a lot of sin, knowing what each of those sins were. Eternally grateful to You, Jesus, very literally.
