2 Samuel 3:38

All the people came to urge David to eat bread while it was yet day; but David swore, saying, “God do so to me, and more also, if I taste bread or anything else, until the sun goes down.”

All the people took notice of it, and it pleased them, as whatever the king did pleased all the people.

So all the people and all Israel understood that day that it was not of the king to kill Abner the son of Ner.

I am weak today, though anointed king. These men, the sons of Zeruiah are too hard for me. May the LORD reward the evildoer according to his wickedness.”
