'Sift' in the Bible

You scrutinize my path and my lying down,And You are intimately acquainted with all my ways.

His breath is like an overflowing river,Which reaches to the neck,To sift the nations back and forth in a sieve [of disaster],And to put in the jaws of the peoples the bridle which leads to ruin.

“For behold, I am commanding,And I shall shake and sift the house of Israel among all nations [and cause it to tremble]Like grain is shaken in a sieve [removing the chaff],But not a kernel [of the faithful remnant] shall fall to the ground and be lost [from My sight].
