33 Heb “he put on a curse as [if it were] his garment.”
34 Heb “and it came like water into his inner being, and like oil into his bones.” This may refer to this individual’s appetite for cursing. For him cursing was as refreshing as drinking water or massaging oneself with oil. Another option is that the destructive effects of a curse are in view. In this case a destructive curse invades his very being, like water or oil. Some who interpret the verse this way prefer to repoint the vav (ו) on “it came” to a conjunctive vav and interpret the prefixed verb as a jussive, “may it come!”
35 Heb “may it be for him like a garment one puts on.”
36 The Hebrew noun מֵזַח (mezakh, “belt; waistband”) occurs only here in the OT. The form apparently occurs in Isa 23:10 as well, but an emendation is necessary there.

In other versions

He clothed himself with cursing as his coat;

may it soak into his body like water,

like oil into his bones!

May it be like a garment that he wraps around him,

like a belt that he puts on every day!

He wore cursing as his garment;

it entered into his body like water,

into his bones like oil.

May it be like a cloak wrapped about him,

like a belt tied forever around him.

He wore cursing like his coat—

let it enter his body like water

and go into his bones like oil.

Let it be like a robe he wraps around himself,

like a belt he always wears.

Cursing is as natural to him as his clothing,

or the water he drinks,

or the rich food he eats.

Now may his curses return and cling to him like clothing;

may they be tied around him like a belt.”

Because he wore a curse as his robe,

let it enter his body like water,

and into his bones like oil.

May it be for him like a garment in which he wraps,

and a belt he continually wears.

As he clothed himself with cursing like as with his garment,

So let it come into his bowels like water,

And like oil into his bones.

Let it be unto him as the garment which covereth him,

And for a girdle wherewith he is girded continually.
