Guard the tongue, keep your vows and fear God, for many words are as empty as dreams.
It is good to spare the tongue, and to keep a steady heart in your eagerness to speak (Ecclesiastes 5:2). For we must not be careless about our words and let slip through the voice whatever comes into the mind, even when it is out of place. Rather, we must bear in mind that, though we stand far from heaven, we speak within God's hearing (Ecclesiastes 5:2), and that it pays to speak without stumbling. Just as all manner of dream images attend the varied cares of the soul, so idle chatter is yoked to folly (Ecclesiastes 5:3).
A promise made by a vow should be fulfilled in deed (Ecclesiastes 5:4). It is the mark of fools to be cast aside (Ecclesiastes 5:4); but you, be truthful, knowing that it is far better for you not to vow, and not to promise to do anything, than to vow and then leave it undone (Ecclesiastes 5:5). You must flee by every means the flood of such fine-sounding words, knowing that God will hear them (Ecclesiastes 5:6). For the one who sets his mind on such things gains nothing but to watch his own works being destroyed by God (Ecclesiastes 5:6). For as many dreams are empty, so too are many words (Ecclesiastes 5:7). The fear of God brings salvation to human beings, but it is rare (Ecclesiastes 5:7).
So there is no need to wonder when you look at the poor being oppressed and at judges who reason dishonestly (Ecclesiastes 5:8). But you must avoid seeming to be greater than those who are more powerful (Ecclesiastes 5:8). For even if you should manage this, still wickedness, of itself, will not rescue you from the terrors that are to come upon you.
