5 But he was wounded because of our transgressions, he was crushed because of our iniquities: the chastisement of our welfare was upon him, and with his stripes we were healed.
Wounded, not pierced.
Cant be Jesus because in a couple of verse later....Isaiah 53:10
Yet it pleased HaShem to crush him by disease; to see if his soul would offer itself in restitution, that he might see his seed, prolong his days, and that the purpose of HaShem might prosper by his hand:
Jesus did not have children, died young.
Artscroll is actually better than this

What is interesting is that Jesus did see His offspring -- for He is their Creator! After being buried for three days He rose again, never to die again. As a result of Jesus’ actions, all those who believe are prospering from his obedience to the Father even on to death.
Not in the natural sense...
He was in the world, and though the world was made through him, the world did not recognize him. He came to that which was his own, but his own did not receive him. Yet to all who received him, to those who believed in his name, he gave the right to become children of God— children born not of natural descent, nor of human decision or a husband's will, but born of God.
John 1:10-13
