BOANERGES
Aramaic word (“bene-regesh”) that means “sons of thunder” and was applied by Jesus to James and John, the sons of Zebedee (Mark 3:17), when he chose them to be his apostles.
Jerome supposed that this nickname referred to his fierce eloquence, and others have attributed it to his vengeful disposition (Lk. 9:52-55 and Mark 9:38), as well as to his pride, citing his mother’s claim of that they would be the ministers of the Lord in the kingdom (Mt. 20:23-24).
It has been suggested that before his conversion they had been revolutionary zealots, but there is no proof of this.
