'Prophet of the Lord' in the Bible

All Israel from Dan to Beer-sheba knew that Samuel was a confirmed prophet of the Lord.

Then Elijah said to the people, “I am the only remaining prophet of the Lord, but Baal’s prophets are 450 men.

But Jehoshaphat said, “Isn’t there a prophet of the Lord here? Let’s inquire of Yahweh through him.”One of the servants of the king of Israel answered, “Elisha son of Shaphat, who used to pour water on Elijah’s hands, is here.”

A prophet of the Lord named Oded was there. He went out to meet the army that came to Samaria and said to them, “Look, the Lord God of your ancestors handed them over to you because of His wrath against Judah, but you slaughtered them in a rage that has reached heaven.
