Isaiah 1:25

I will turn My hand against you; I will thoroughly purge your dross; I will remove all your impurities.

And I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin:

Note purely: Heb. according to pureness

I will turn my hand on you, thoroughly purge away your dross, and will take away all your tin.

Note tin is a metal that is separated from silver during the refining and purification process.

and I will turn my hand upon thee, and thoroughly purge away thy dross, and will take away all thy tin;
