'Someone' in the Bible

when someone told me, 'Behold, Saul is dead,' thinking to have brought good news, I took hold of him, and killed him in Ziklag, which was the reward I gave him for his news.

Someone told David, saying, "Ahithophel is among the conspirators with Absalom." David said, "Yahweh, please turn the counsel of Ahithophel into foolishness."
