Matthew 20:23

“And he saith unto them, ye shall drink indeed of my cup, etc.] Not of the selfsame, but of what was like unto it; meaning, that they should endure much persecution for his name’s sake, as all that will live godly in Christ Jesus must expect in one shape or another. Thus James, who was one of these persons, was slain with the sword by Herod; John, the other, was imprisoned, and beaten by the order of the Jewish sanhedrim, was banished into the isle of Patmos by Domitian; and, some say, was cast into a cauldron of boiling oil, though saved in it: so that these words seem to be a prophecy of what they should suffer for Christ, instead of enjoying places of worldly honour and profit under him,…”

He only asserts, that he gives it to none but those for whom it is originally prepared; namely, those who endure to the end in the faith that worketh by love. Matthew 20:25”

“20:23 You will indeed: James was eventually martyred (Acts 12:2), and John suffered significant persecution (Acts 4:3; 5:40; Rev 1:9).”

“Ye: Act 12:2; Rom 8:17; Co2 1:7; Col 1:24; Ti2 2:11, Ti2 2:12; Rev 1:9 to sit: Rather, "to sit on my right hand, and on my left, is not mine to give, except to them for whom it is prepared of my Father." for: Mat 25:34; Mar 10:40; Co1 2:9; Heb 11:16 Matthew 20:24”
