Luke 22:19

And he took bread, and when he had given thanks, he brake it, and gave to them, saying, This is my body which is given for you: this do in remembrance of me.

This was the beginning of the institution of the Lord's Supper, the same being after the last meal they had just shared was concluded, placing it after (8) and before (9) in the above pattern.

For full comment on "transubstantiation" and other questions, see parallel with comments in my Commentary on Matthew. Here the eternal commandment of remembering the Saviour was uttered. The vast difference in Judaism and Christianity is in this very thing. Under the Law of Moses, there was a "remembrance" made of sin upon every solemn occasion of worship, even upon the day of Atonement; but in Christianity, there is no more a remembrance of sin, but of the Lamb of God who took away the sins of the world. See elaboration of this in my Commentary on Hebrews, Hebrews 10:3-4.
