11 Heb “(with) toil she has wearied.” The meaning of the statement is unclear in the Hebrew text; some follow the and delete it. The first word in the statement (rendered “toil” in the literal translation above) occurs only here in the OT, and the verb “she has wearied” lacks a stated object. Elsewhere the Hiphil of the verb refers to wearying someone or trying someone’s patience. The feminine subject is apparently the symbolic pot.
12 Heb “does not go out.”
13 Heb “in fire its rust.” The meaning of the expression is unclear. The translation understands the statement as a command to burn the rust away. See D. I. Block, Ezekiel (), 1:.

In other versions

She has wearied herself with toil; its abundant corrosion does not go out of it. Into the fire with its corrosion!

It has frustrated all efforts;

its heavy deposit has not been removed,

not even by fire.

It has frustrated every effort;

its thick corrosion will not come off.

Into the fire with its corrosion!

But it’s hopeless;

the corruption can’t be cleaned out.

So throw it into the fire.

Through effort she has caused weariness; its thick rust went not out of it. Its rust! Into the fire with its rust!

She hath wearied herself with lies, and her great scum went not forth out of her: her scum shall be in the fire.
