20 Then the mother of the sons of Zebedee came to him with her sons, and kneeling before him, she asked a favor of him. 21 And he said to her, "What do you want?" She said to him, "Declare that these two sons of mine will sit, one at your right hand and one at your left, in your kingdom." 22 But Jesus answered, "You do not know what you are asking. Are you able to drink the cup that I am about to drink?" They said to him, "We are able." 23 He said to them, "You will indeed drink my cup, but to sit at my right hand and at my left, this is not mine to grant, but it is for those for whom it has been prepared by my Father." 24 When the ten heard it, they were angry with the two brothers. 25 But Jesus called them to him and said, "You know that the rulers of the Gentiles lord it over them, and their great ones are tyrants over them.

Commentary on Matthew 20:20-28
(Read Matthew 20:20-28)
The sons of Zebedee abused what Christ said to comfort the disciples. Some cannot have comforts but they turn them to a wrong purpose. Pride is a sin that most easily besets us; it is sinful ambition to outdo others in pomp and grandeur. To put down the vanity and ambition of their request, Christ leads them to the thoughts of their sufferings. It is a bitter cup that is to be drunk of; a cup of trembling, but not the cup of the wicked. It is but a cup, it is but a draught, bitter perhaps, but soon emptied; it is a cup in the hand of a Father, Philippians 1:29. But they knew not what Christ's cup was, nor what his baptism. Those are commonly most confident, who are least acquainted with the cross. Nothing makes more mischief among brethren, than desire of greatness. And we never find Christ's disciples quarrelling, but something of this was at the bottom of it. That man who labours most diligently, and suffers most patiently, seeking to do good to his brethren, and to promote the salvation of souls, most resembles Christ, and will be most honoured by him to all eternity. Our Lord speaks of his death in the terms applied to the sacrifices of old. It is a sacrifice for the sins of men, and is that true and substantial sacrifice, which those of the law faintly and imperfectly represented. It was a ransom for many, enough for all, working upon many; and, if for many, then the poor trembling soul may say, Why not for me?
