The prudent keeps silent at such a time

It is better for a wise man to remain silent in this situation. It would be better to say something than to not respond or to keep things a secret.

("Therefore the wise man in the time of the day will be likened, for it is an evil time" - Amos 5:13, and so: "And he will make me understand then in the land (Genesis 12:6) that the land of Canaan will be divided from one hand to another. And if we are not like that, then there is a secret for him. And the wise man will be likened" - Ibn Ezra in Genesis 12:6, and so: "Is this why we are being set up as a barrier before us, because we are not "Remember, my heart is weary of recounting in the power of His praise, the Holy One did not speak or half-speak, and the wise man in his time was like a rabbi" - Introduction to the Book of Proverbs by Rabbi Nachman of Breslau)
