'Says the Lord' in the Bible

For it is written [Isa. 45:23], "As surely as I am the living God, says the Lord, everyone's knee will bow before me, and everyone's mouth will confess to [or, praise] God."

It is written in the law [Isa. 28:11f], "I [i.e., God] will speak to these people [i.e., the Israelites] by men with foreign languages and through the lips of strangers, and even then they will not listen to me, says the Lord."

[It will] not be like the Agreement that I made with their forefathers on the day I took them by the hand to lead them out of the country of Egypt. For they did not [continue to] keep my Agreement, so I did not regard them [as acceptable], says the Lord.

For this is the Agreement that I will make with the people of Israel in the coming days, says the Lord: I will put my laws into their minds, and I will also write them on their hearts. And I will be their God and they will be my people.

"I am the Alpha and the Omega" [Note: These are the first and last letters of the Greek alphabet, and indicate "the beginning and the end" See 21:6], says the Lord God Almighty, who is [in the present], and who was [in the past] and who will come [in the future].
