A shrewd person conceals knowledge,
but a foolish heart publicizes stupidity.
A gossip goes around revealing a secret,
but a trustworthy person keeps a confidence.
Do not curse the king even in your thoughts,
and do not curse a rich person even in your bedroom,
for a bird of the sky may carry the message,

1 Samuel 27:11
David did not let a man or woman live to be brought to Gath, for he said, “Or they will inform on us and say, ‘This is what David did.’” This was David’s custom during the whole time he stayed in the Philistine territory.
2 Samuel 1:20
Do not tell it in Gath,
don’t announce it in the marketplaces of Ashkelon,
or the daughters of the Philistines will rejoice,
and the daughters of the uncircumcised will gloat.
Don’t announce it in Gath,
don’t weep at all.
Roll in the dust in Beth-leaphrah.
2 Kings 9:15
But King Joram had returned to Jezreel to recover from the wounds that the Arameans had inflicted on him when he fought against Aram’s King Hazael. Jehu said, “If you commanders wish to make me king, then don’t let anyone escape from the city to go tell about it in Jezreel.”
1 Samuel 21:2
David answered Ahimelech the priest, “The king gave me a mission, but he told me, ‘Don’t let anyone know anything about the mission I’m sending you on or what I have ordered you to do.’ I have stationed my young men at a certain place.
Then Zedekiah warned Jeremiah, “Don’t let anyone know about these things or you will die.
So the commander dismissed the young man and instructed him, “Don’t tell anyone that you have informed me about this.”
