'Lord Shall' in the Bible

“The anger of the Lord will not turn backUntil He has set in motion and accomplished the thoughts and intentions of His heart;In the last days you will clearly understand it.

“Therefore prophesy all these words against them and say to them:‘The Lord will roar from on highAnd utter His voice from His holy dwelling;He will roar mightily against His fold and pasture.He will jubilantly shout like those who tread the grapes [in the wine press],Against all the inhabitants of the earth.

“And those slain by the Lord on that day will be from one end of the earth to the other end of the earth. They will not be lamented (mourned over with expressions of grief) or gathered or buried; they will be like dung on the ground.

The fierce (righteous) anger of the Lord will not turn backUntil He has fulfilled and until He has accomplishedThe intent of His heart (mind);In the latter days you will understand this.
