Isaiah 53:1-3

1 Who has believed our message

and to whom has the arm of the LORD been revealed?
2 He grew up before him like a tender shoot,

and like a root out of dry ground.

He had no beauty or majesty to attract us to him,

nothing in his appearance that we should desire him.
3 He was despised and rejected by men,

a man of sorrows, and familiar with suffering.

Like one from whom men hide their faces

he was despised, and we esteemed him not.

In the beginning of this chapter, the prophecy switches to prophetic past tense which is the natural tense for those of us who now live after these events.

Who has believed... revealed implies that few would believe when Christ came. This was certainly fulfilled when Christ came and died. Israel did not recognize the arm of the Lord and for this reason He was despised and rejectd by men. But even though Christ was despised and rejected and misunderstood, God watched and guided every detail of Christ's life as shown in 2a.

No stately form means that though Christ was and is the King Eternal, He did not come with any royal garb or emblem that showed Him to be a king. And though His way did not make sense to man, the Lord's might was in this all the way.

Lastly, this section begins the description of Christ's atoning death, which will be further discussed in the coming verses. For now, note that before His death, Christ was first despised by men and forsaken by them. But notice that these verses do not simply leave the blame on others, but is all inclusive in stating that we esteemed Him not. Christ's blood is on all our hands and tomorrow we will see what this means for us.
