8 Nations, headed by Edom, are the object of the Lord’s anger (see v. 6). He compares military slaughter to stomping on grapes in a vat.
9 Heb “and I stained.” For discussion of the difficult verb form, see II גאל. Perhaps the form is mixed, combining the first person forms of the imperfect (note the alef prefix) and perfect (note the תי- ending).

“I have trodden the winepress alone,

and from the peoples no one was with me;

I trod them in my anger

and trampled them in my wrath;

their lifeblood spattered on my garments,

and stained all my apparel.

“I have trodden the winepress alone;

from the nations no one was with me.

I trampled them in my anger

and trod them down in my wrath;

their blood spattered my garments,

and I stained all my clothing.

I trampled the winepress alone,

and no one from the nations was with me.

I trampled them in my anger

and ground them underfoot in my fury;

their blood spattered my garments,

and all my clothes were stained.

“I have been treading the winepress alone;

no one was there to help me.

In my anger I have trampled my enemies

as if they were grapes.

In my fury I have trampled my foes.

Their blood has stained my clothes.

“I have trodden the winepress alone,

and there was no man from the peoples with me.

And I trod them in my anger,

and I trampled them in my wrath,

and spattered their juice on my garments,

and stained all my clothing,

I have trodden the winepress alone;

And of the people there was none with me:

For I will tread them in mine anger,

And trample them in my fury;

And their blood shall be sprinkled upon my garments,

And I will stain all my raiment.
