12 Brother will betray brother to death, and a father his child, and children will rise against parents and have them put to death;

Matthew Henry's Commentary on Mark 13:12

Commentary on Mark 13:5-13

(Read Mark 13:5-13)

Our Lord Jesus, in reply to the disciples' question, does not so much satisfy their curiosity as direct their consciences. When many are deceived, we should thereby be awakened to look to ourselves. And the disciples of Christ, if it be not their own fault, may enjoy holy security and peace of mind, when all around is in disorder. But they must take heed that they are not drawn away from Christ and their duty to him, by the sufferings they will meet with for his sake. They shall be hated of all men: trouble enough! Yet the work they were called to should be carried on and prosper. Though they may be crushed and borne down, the gospel cannot be. The salvation promised is more than deliverance from evil, it is everlasting blessedness.
