'He is the Lord' in the Bible

So I have given him to the Lord; for all his life he is the Lord's. Then he gave the Lord worship there.

So Samuel told him everything and did not hide anything from him. Eli responded, “He is the Lord. He will do what He thinks is good.”

He said to his men, “I swear before the Lord: I would never do such a thing to my lord, the Lord’s anointed. I will never lift my hand against him, since he is the Lord’s anointed.”

Behold, your eyes have seen today how the Lord had given you into my hand in the cave. Some told me to kill you, but I spared you; I said, ‘I will not reach out my hand against my lord, for he is the Lord’s anointed.’
