The Wisdom of Jesus the Son of Sirach, or Ecclesiasticus 20:7 주석

For those who take notice of what is evil in their neighbours, and yet refrain their tongue in silence, withdraw, as it were, the aid of medicine from observed sores, and become the causers of death, in that they would not cure the venom which they could have cured. The tongue, therefore, should be discreetly curbed, not tied up fast. For it is written, "A wise man will hold his tongue until the time"; in order, assuredly, that, when he considers it opportune, he may relinquish the censorship of silence, and apply himself to the service of utility by speaking such things as are fit. And again it is written, "A time to keep silence, and a time to speak." For, indeed, the times for changes should be discreetly weighed, lest either, when the tongue ought to be restrained, it run loose to no profit in words, or, when it might speak with profit, it slothfully restrain itself. Considering which thing well, the Psalmist says, "Set a watch, O Lord, on my mouth, and a door round about my lips." For he seeks not that a wall should be set on his lips, but a door: that is, what is opened and shut. Whence we, too, ought to learn warily, to the end that the voice discreetly and at the fitting time may open the mouth, and at the fitting time silence close it. But, on the other hand, those who spend time in much speaking are to be admonished that they vigilantly note from what a state of rectitude they fall away when they flow abroad in a multitude of words. For the human mind, after the manner of water, when closed in, is collected unto higher levels, in that it seeks again the height from which it descended; and, when let loose, it falls away in that it disperses itself unprofitably through the lowest places.
