'Says the Lord' in the Bible

‘Heaven is My throne,And the earth is the footstool for My feet;What kind of house will you build for Me?’ says the Lord,‘Or what place is there for My rest?

Says the Lord,Who has been making these things known from long ago.

Beloved, never avenge yourselves, but leave the way open for God’s wrath [and His judicial righteousness]; for it is written [in Scripture], “Vengeance is Mine, I will repay,” says the Lord.

For it is written [in Scripture],“As I live, says the Lord, every knee shall bow to Me,And every tongue shall give praise to God.”

It is written in the Law, “By men of strange tongues and by the lips of foreigners I will speak to this people, and not even then will they listen to Me,” says the Lord.

“So come out from among unbelievers and be separate,” says the Lord,“And do not touch what is unclean;And I will graciously receive you and welcome you [with favor],

And I will be a Father to you,And you will be My sons and daughters,”Says the Lord Almighty.

However, God finds fault with them [showing its inadequacy] when He says,“Behold, the days will come, says the Lord,When I will make and ratify a new covenantWith the house of Israel and with the house of Judah;

Not like the covenant that I made with their fathersOn the day when I took them by the handTo lead them out of the land of Egypt;For they did not abide in My covenant,And so I withdrew My favor and disregarded them, says the Lord.

“For this is the covenant that I will make with the house of IsraelAfter those days, says the Lord:I will imprint My laws upon their minds [even upon their innermost thoughts and understanding],And engrave them upon their hearts [effecting their regeneration].And I will be their God,And they shall be My people.

“This is the covenant that I will make with themAfter those days, says the Lord:I will imprint My laws upon their heart,And on their mind I will inscribe them [producing an inward change],”He then says,

For we know Him who said, “Vengeance is Mine [retribution and the deliverance of justice rest with Me], I will repay [the wrongdoer].” And again, “The Lord will judge His people.”

“I am the Alpha and the Omega [the Beginning and the End],” says the Lord God, “Who is [existing forever] and Who was [continually existing in the past] and Who is to come, the Almighty [the Omnipotent, the Ruler of all].”
