'Fault' in the Bible

Then the Philistine commanders asked, “What are these Hebrews doing here?”Achish answered the Philistine commanders, “That is David, servant of King Saul of Israel. He has been with me a considerable period of time. From the day he defected until today, I’ve found no fault with him.”

So Achish summoned David and told him, “As the Lord lives, you are an honorable man. I think it is good to have you working with me in the camp, because I have found no fault in you from the day you came to me until today. But the leaders don’t think you are reliable.
