Be not rash with thy mouth, and let not thine heart be hasty
to utter [any] thing before God
In private conversation care should be taken that no rash and unadvised words be spoken in haste, as were by Moses and David; and that no evil, nor even any idle word he uttered, since from, the abundance of the heart the mouth is apt to speak, and all is before, the Lord; not a word in the tongue but is altogether known by him, and must be accounted for to him, ( Psalms 106:33 ) ( 116:11 ) ( 139:4 ) ( Matthew 12:34-37 ) . Jerom interprets this of words spoken concerning God; and careful men should be of what they say of him, of his nature and perfections, of his persons, and of his works; and it may be applied to a public profession of his name, and of faith in him; though this should be done with the heart, yet the heart and tongue should not be rash and hasty in making it; men should consider what they profess and confess, and upon what foot they take up and make a profession of religion; whether they have the true grace of God or no: and it will hold true of the public ministry of the word, in which everything that comes uppermost in the mind, or what is crude and undigested, should not be, uttered; but what ministers have thought of, meditated on, well weighed in their minds, and properly digested. Some understand this of rash vows, such as Jephthah's, is supposed to be, which are later repented of; but rather speaking unto God in prayer is intended. So the Targum,
``thy, heart shall not hasten to bring out speech at the time thou prayest before the Lord;''anything and everything that comes up into the mind should not be, uttered before God; not anything rashly and hastily; men should consider before they speak to the King of kings; for though set precomposed forms of prayer are not to be used, yet the matter of prayer should be thought of beforehand; what our wants are, and what we should ask for; whether for ourselves or others; this rule I fear we often offend against: the reasons follow; for God [is] in heaven, and thou upon earth;
