Ecclesiastes 5:2

“Be not rash with thy mouth, and let not thine heart be hasty to utter [any] thing before God, etc.] 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, (<19A633>Psalm 106:33 116:11 139:4 <401234> 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;…”

“rash--opposed to the considerate reverence ("keep thy foot," Ecc 5:1). This verse illustrates Ecc 5:1, as to prayer in the house of God ("before God," Isa 1:12); so Ecc 5:4-6 as to vows.

“not rash: Gen 18:27, Gen 18:30, Gen 18:32, Gen 28:20, Gen 28:22; Num 30:2-5; Jdg 11:30; 1Sam. 14:24-45; Mar 6:23 thing: or, word for: Psa 115:3; Isa 55:9; Mat 6:9, let thy , Ecc 5:3, Ecc 5:7; Pro 10:19; Mat 6:7; Jam 3:2 Ecclesiastes 5:3”

“"Be not hasty with thy mouth, and let not thy heart hasten to speak a word before God: for God is in heaven, and thou art upon earth; therefore let thy words be few. For by much business cometh dreaming, and by much talk the noise of fools." As we say in German: auf Flgeln fliegen \[to flee on wings\], auf Einem Auge nicht sehen \[not to see with one eye\], auf der Flte blasen \[to blow on the flute\], so in Heb. we say that one slandereth with (auf) his tongue ( Psa 15:3), or, as here, that he hasteth with his mouth, i.e., is forward with his mouth, inasmuch as the word goes before the thought. It is the same usage as when the post-bibl. Heb., in contradistinction to התורה שׁבּכתב, the law…”
