And Jesus answered and said unto them
Not to indulge their curiosity, but to instruct them in things useful to be known, and which might be cautions to them and others, against deceivers; confirm them in the faith of himself, when they should see his predictions accomplished; and be directions to them, of what might shortly be expected.
Take heed that no man deceive you:
by pretending to come from God with a new revelation, setting himself up for the Messiah, after my departure; suggesting himself to be the person designed by God to be the deliverer of Israel, and to be sent by him, to set up a temporal kingdom, in great worldly splendour and glory; promising great names, and high places of honour and trust in it; things which Christ knew his disciples were fond of, and were in danger of being ensnared by; and therefore gives them this suitable and seasonable advice, and caution.
