'Thus Says the Lord' in the Bible

And there came a man of God unto Eli, and said unto him, Thus says the LORD, Did I plainly appear unto the house of your father, when they were in Egypt in Pharaoh's house?

And said unto the children of Israel, Thus says the LORD God of Israel, I brought up Israel out of Egypt, and delivered you out of the hand of the Egyptians, and out of the hand of all kingdoms, and of them that oppressed you.

Thus says the LORD of hosts, I remember that which Amalek did to Israel, how he laid wait for him in the way, when he came up from Egypt.
