Ten angry men (Mt 20:24-20:24)

“When the ten heard it,

They were angry

With the two brothers.”


καὶ ἀκούσαντες οἱ δέκα ἠγανάκτησαν περὶ τῶν δύο ἀδελφῶν.


There is something similar to this in Mark, chapter 10:41, but slightly different.  There was a little dissention here.  When the ten other leaders or apostles heard (καὶ ἀκούσαντες οἱ δέκα) about this situation of the sons of Zebedee, James and John, they were angry, incensed, or indignant with these two brothers (ἠγανάκτησαν περὶ τῶν δύο ἀδελφῶν).  Why did they want to be prominent?  What about them?  Were not all the apostles equal?  What made these two so important?
