Bad information...

Then the Ziphites went up to Saul at Gibeah, saying, “Is not David hiding among us in the strongholds at Horesh, on the hill of Hachilah, which is south of Jeshimon? Now come down, O king, according to all your heart's desire to come down, and our part shall be to surrender him into the king's hand.” And Saul said, “May you be blessed by the LORD, for you have had compassion on me. Go, make yet more sure. Know and see the place where his foot is, and who has seen him there, for it is told me that he is very cunning. See therefore and take note of all the lurking places where he hides, and come back to me with sure information. Then I will go with you. And if he is in the land, I will search him out among all the thousands of Judah.” And they arose and went to Ziph ahead of Saul. Now David and his men were in the wilderness of Maon, in the Arabah to the south of Jeshimon. (1 Samuel 23:19-24 ESV)
The Ziphites gave Saul bad information. Not only were they incorrect about David's location, as he had moved on. More importantly, if it were correct, it would be bad information, because it fueled the fire of Saul's jealousy and hatred. It may have gotten them on the good side of Saul for a time, but it was divisive of God's people, getting them to pit the two against one another. Whenever division seeps into God's people, much of what is "passed on" is bad information, only meant to bring about bad behavior that makes one look better by comparison, and takes advantage of a sad situation. Let us make sure today that we are only bearers of good information that shares truth, and does so with pure motives and good wishes.
