Charles Ellicott Commentary Matthew 10:21

"And brother shall deliver up brother to death, and the father his child: and children shall rise up against parents, and cause them to be put to death." — Matthew 10:21 (ASV)

The brother—In the Greek, the nouns are used without the article, brother shall deliver up brother, and are thus, perhaps, more powerful as statements of what would often happen. Our English idiom, however, allows the use of the article with nearly the same meaning. The words reproduce the prophecy of Micah 7:6 almost word for word. In that passage, they are followed by the prophet’s expression of his faith: Therefore I will look unto the Lord; I will wait for the God of my salvation. This corresponds to the “endurance” of which our Lord speaks in the next verse.
