Matthew 6:7

But when ye pray, use not vain repetitions--"Babble not" would be a better rendering, both for the form of the word--which in both languages is intended to imitate the sound--and for the sense, which expresses not so much the repetition of the same words as a senseless multiplication of them; as appears from what follows. as the heathen do: for they think that they shall be heard for their much speaking--This method of heathen devotion is still observed by Hindu and Mohammedan devotees. With the Jews, says LIGHTFOOT, it was a maxim, that "Every one who multiplies prayer is heard." In the Church of Rome, not only is it carried to a shameless extent, but, as THOLUCK justly observes, the very prayer which our Lord gave as an antidote to vain repetitions is the most abused to this superstitious end; the number of times it is repeated counting for so much more merit. Is not this just that characteristic feature of heathen devotion which our Lord here condemns? But praying much, and using at times the same words, is not here condemned, and has the example of our Lord Himself in its favor.

Christ having, in the former chapter, armed his disciples against the corrupt doctrines and opinions of the scribes and Pharisees, especially in their expositions of the law (that was called their leaven, Mat 16:12), comes in this chapter to warn them against their corrupt practices, against the two sins which, though in their doctrine they did not justify, yet in their conversation they were notoriously guilty of, and so as even to recommend them to their admirers: these were hypocrisy and worldly-mindedness, sins which, of all others, the professors of religion need most to guard against, as sins that most easily beset those who have escaped the grosser pollutions that are in the world through lust, and which are therefore highly dangerous. We are here cautioned, I. Against hypocrisy; we must not be as the hypocrites are, nor do as the hypocrites do. 1. In the giving of alms (Mat 6:1-4). 2. In prayer (Mat 6:5-8). We are here taught what to pray for, and how to pray (Mat 6:9-13); and to forgive in prayer (Mat 6:14, Mat 6:15). 3. In fasting (Mat 6:16-18). II. Against worldly-mindedness, 1. In our choice, which is the destroying sin of hypocrites (Mat 6:19-24). 2. In our cares, which is the disquieting sin of many good Christians (Mat 6:25-34).

6:7-8 God cannot be coaxed by endless repetition. The Lord’s Prayer (6:9-13) is a model of simplicity in contrast with pagan wordiness.
