'Thoroughly' in the Bible

“And I will turn My hand against you,And will [thoroughly] purge away your dross as with lyeAnd remove all your tin (impurity).

For the high and exalted OneHe who inhabits eternity, Whose name is Holy says this,“I dwell on the high and holy place,But also with the contrite and humble in spiritIn order to revive the spirit of the humbleAnd to revive the heart of the contrite [overcome with sorrow for sin].
