"5 Your lamb shall be without blemish, a male of the first year; ye shall take it from the sheep, or from the goats; 6 and ye shall keep it unto the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at dusk. 7 And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it." Exodus 12
The blood of the Pascal lamb was not a sign of forgiveness of sins, but of obedience to given instructions. This is in essence what Yeshuah represented; like his father Abraham, he took obedience to the instructions of the Most High completely to heart, even onto personal sacrifice.
His death as one who was found without blemish was a testament against the people, not a remittance of sins. It showed clearly that their hearts were stony and this is what brought about the final collapse of the temple and the dispersal of the people. Remember, he said he was sent to the "lost sheep of the house of Israel", and his main opposition came from the midst of his own people, i.e. the Judeans of his time.
He sent his disciples in to the nations to search out the "lost sheep of the house of Israel" because they were not in the land at the time of his teaching and his message was for them. He didn't die to take away the sins of the world, but to fulfill the prophecy that, even though he was without blemish, his own people would persecute and reject him.
He was a Judean Hebrew Israelite.
"7 He was oppressed, though he humbled himself and opened not his mouth; as a lamb that is led to the slaughter, and as a sheep that before her shearers is dumb; yea, he opened not his mouth. 8 By oppression and judgment he was taken away, and with his generation who did reason? for he was cut off out of the land of the living, for the transgression of my people to whom the stroke was due." Isaiah 53
The Judeans of the time should have received the Judgment of YHWH, but Yeshuah, like Moses in his day, made intercession and suffered the burden of the judgment that was for the sins of his people at that time. And, as with Moses, judgment delayed was not judgment denied; the house of Judah was dispersed from the land in the years that followed.
"28 In those days they shall say no more: 'The fathers have eaten sour grapes, and the children's teeth are set on edge.' 29 But every one shall die for his own iniquity; every man that eateth the sour grapes, his teeth shall be set on edge. 30 Behold, the days come, saith YHWH, that I will make a new covenant with the house of Israel, and with the house of Judah;" Jeremiah 31
No one is dying for someone else's sins anymore....
