20 Then came to him the mother of the sons of Zebedee with her sons, worshipping [him], and asking a certain thing of him. 21 And he said unto her, What wouldest thou? She saith unto him, Command that these my two sons may sit, one on thy right hand, and one on thy left hand, in thy kingdom. 22 But Jesus answered and said, Ye know not what ye ask. Are ye able to drink the cup that I am about to drink? They say unto him, We are able. 23 He saith unto them, My cup indeed ye shall drink: but to sit on my right hand, and on [my] left hand, is not mine to give; but [it is for them] for whom it hath been prepared of my Father. 24 And when the ten heard it, they were moved with indignation concerning the two brethren.

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?
