'Someone' in the Bible

Someone reported this to Saul: "Right now the army is sinning against the LORD by eating meat with the blood." He said, "You have acted treacherously. Roll a large stone to me today."

Then Samuel told Jesse, "Are these all the young men?" He said, "There yet remains the youngest one, and right now he's tending the sheep." Samuel told Jesse, "Send someone to get him, for we won't do anything else until he arrives here."

Someone replied, "They're at Naioth in Ramah." Saul went to Naioth in Ramah, and the Spirit of God came on him also. He continued in prophetic ecstasy until he came to Naioth in Ramah.

As long as Jesse's son lives on the earth, neither you nor your kingdom will be established! Now send someone and bring David to me. He's a dead man!"

Someone told David, "Look, the Philistines are fighting at Keilah and are plundering the threshing floors."

Now, don't let my blood fall to the ground away from the LORD's presence. Indeed, the king of Israel has come out to seek a single flea, like someone hunts a partridge in the mountains."
