'Let thy words be few.' The heathen 'think that they shall be heard for much speaking.' It needs not to tell our wants in many words to One who knows them altogether, any more than a child needs many when speaking to a father or mother. But 'few' must be measured by the number of needs and desires. The shortest prayer, which is not animated by a consciousness of need and a throb of desire, is too long; the longest, which is vitalised by these, is short enough. What becomes of the enormous percentage of public and private prayers, which are mere repetitions, said because they are the right thing to say, because everybody always has said them, and not because the man praying really wants the things he asks for, or expects to get them any the more for asking?
Verse 3 gives a reason for the exhortation, 'A dream comes through a multitude of business'--when a man is much occupied with any matter, it is apt to haunt his sleeping as well as his waking thoughts. 'A fool's voice comes through a multitude of words.' The dream is the consequence of the pressure of business, but the fool's voice is the cause, not the consequence, of the gush of words. What, then, is the meaning? Probably that such a gush of words turns, as it were, the voice of the utterer, for the time being, into that of a fool. Voluble prayers, more abundant than devout sentiments or emotions, make the offerer as a 'fool' and his prayer unacceptable.
The third direction refers to conduct after worship. It lays down the general principle that vows should be paid, and that swiftly. A keen insight into human nature suggests the importance of prompt fulfilment of the vows; for in carrying out resolutions formed under the impulse of the sanctuary, even more than in other departments, delays are dangerous. Many a young heart touched by the truth has resolved to live a Christian life, and has gone out from the house of God and put off and put off till days have thickened into months and years, and the intention has remained unfulfilled for ever. Nothing hardens hearts, stiffens wills, and sears consciences so much as to be brought to the point of melting, and then to cool down into the old shape. All good resolutions and spiritual convictions may be included under the name of vows; and of all it is true that it is better not to have formed them, than to have formed and not performed them.
Verses 6 and 7 are obscure. The former seems to refer to the case of a man who vows and then asks that he may be absolved from his vow by the priest or other ecclesiastical authority. His mouth--that is, his spoken promise--leads him into sin, if he does not fulfil it (comp. Deut. xxiii, 21, 22). He asks release from his promise on the ground that it is a sin of weakness. The 'angel' is best understood as the priest (messenger), as in Malachi ii.7. Such a wriggling out of a vow will bring God's anger; for the 'voice' which promised what the hand will not perform, sins.
Verse 7 is variously rendered. The Revised Version supplies at the beginning, 'This comes to pass,' and goes on 'through the multitude of dreams and vanities and many words.' But this scarcely bears upon the context, which requires here a reason against rash speech and vows. The meaning seems better given, either by the rearranged text which Delitzsch suggests, 'In many dreams and many words there are also many vanities' (so, substantially, the Auth. Ver.), or as Wright, following Hitzig, etc., has it, 'In the multitude of dreams are also vanities, and [in] many words [as well].' The simile of verse 3 is recurred to, and the whirling visions of unsubstantial dreams are likened to the rash words of voluble prayers in that both are vanity. Thus the writer reaches his favourite thought, and shows how vanity infects even devotion. The closing injunction to 'fear God' sets in sharp contrast with faulty outward worship the inner surrender and devotion, which will protect against such empty hypocrisy. If the heart is right, the lips will not be far wrong.
