The below scripture is about the Last Supper...where Jesus institutes the sacrament:
8 And he sent Peter and John, saying, Go and prepare us the passover, that we may eat.
10 And he said unto them, Behold, when ye are entered into the city, there shall a man meet you, bearing a pitcher of water; follow him into the house where he entereth in.
11 And ye shall say unto the goodman of the house, The Master saith unto thee, Where is the guestchamber, where I shall eat the passover with my disciples?
16 For I say unto you, I will not any more eat thereof, until it be fulfilled in the kingdom of God.
18 For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God shall come.
19 ¶And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
