John Trapp on Matthew 26:29

Verse 29. I will not drink hence forth] So he takes his farewell of his Disciples: alluding, likely, to that custom among them of Poculum [non-Latin text not transcribed]. drinking no more, till the next day after they had drunk, each his part, of the parting-cup. Drink it new with you in my Fathers kingdom] Understand it either of the kingdom of grace (Peter saith, that he and others did eat and drink with Christ after he rose from the dead, Act. 10. 41. we also feast with him dayly by faith, at his table especially, where he is both feast-maker and feast-master,) Or of his kingdom of glory, frequently and fitly set forth by the similitude of a sumptuous supper, Matth. 8. Luk. 14. &c. such as to which all other feasts are but hunger.
