OK, but now that you mention it, it does say that the entire law would be fulfilled. Very interesting.
There are other references to fulfilment.
Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders,
Saying, I have sinned in that I have betrayed the innocent blood. And they said, What [is that] to us? see thou [to that].
And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
And the chief priests took the silver pieces, and said, It is not lawful for to put them into the treasury, because it is the price of blood.
And they took counsel, and bought with them the potter's field, to bury strangers in.
Wherefore that field was called, The field of blood, unto this day.
Then was fulfilled that which was spoken by Jeremy the prophet, saying, And they took the thirty pieces of silver, the price of him that was valued, whom they of the children of Israel did value;
And gave them for the potter's field, as the Lord appointed me.
Matthew 27:3-10
... but it wasn't Jeremy/Jeremiah, but Zechariah
And I said unto them, If ye think good, give [me] my price; and if not, forbear. So they weighed for my price thirty [pieces] of silver.
And YHWH said unto me, Cast it unto the potter: a goodly price that I was prised at of them. And I took the thirty [pieces] of silver, and cast them to the potter in the house of YHWH.
Zechariah 11:12-13
... and according to Peter, Judas didn't return the silver:
Men [and] brethren, this scripture must needs have been fulfilled, which the Holy Ghost by the mouth of David spake before concerning Judas, which was guide to them that took Jesus.
For he was numbered with us, and had obtained part of this ministry.
Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.
Acts 1:16-18
... but Peter does associate Judas with Psalm 69:
They that hate me without a cause are more than the hairs of mine head: they that would destroy me, [being] mine enemies wrongfully, are mighty: then I restored [that] which I took not away.
Psalms 69:4
