23 For I haue receiued of the Lord that which also I deliuered vnto you, that the Lord Iesus, the same night in which he was betrayed, tooke bread:
24 And when he had giuen thanks, he brake it, and sayd, Take, eate, this is my body, which is broken for you: this doe in remembrance of mee.
25 After the same manner also hee tooke the cup when he had supped, saying, This cup is the new Testament in my blood: this do ye, as oft as ye drinke it, in remembrance of me.
26 For as often as ye eate this bread, and drinke this cup, yee doe shew the Lords death till he come.
