She hath wearied herself with toil; yet her great rust goeth not forth out of her; her rust goeth not forth by fire.

It has frustrated every effort; its thick rust has not been removed, even by the fire.

With sorrows she hath wearied herself, And the abundance of her scum goeth not out of her, In the fire is her scum.

She hath exhausted [her] labours, yet her great rust goeth not forth out of her: let her rust be in the fire.
