Rashi on the Prophets and Writings

Behold I send My angel to put the wicked away.
and the angel of the covenant who avenges the revenge of the covenant.
and he will clear a way of the wicked.
the Lord Whom you seek The God of justice.

Now who can abide This is synonymous with; וּמִי יָכִיל
and who will stand Will be able to stand.
and like fullers’ soap Like soap used by the fullers, which removes the entire stain. So will he remove all the wickedness. and like soap It is an herb which removes stains, erbe savonijere in Old French, probably soapwort. The word בֹּרִית signifies a thing that cleans and purifies, as in (Ps. 73:1), “to the pure of heart.”

And he shall sit refining He will free himself from all his affairs to be like a refiner, who refines and purifies silver.

For I, the Lord, have not changed Although I keep back My anger for a long time, My mind has not changed from the way it was originally, to love evil and to hate good.
and you, the sons of Jacob Although you die in your evil, and I have not requited the wicked in their lifetime
you have not reached the end You are not finished from before Me, for I have left over the souls to be requited in Gehinnom. And so did Jonathan render. And you of the House of Jacob, who think that whoever dies in this world, his verdict has already ended, that is to say, you think that My verdict has been nullified, that he will no longer be punished. Our Sages (Sotah 9a), however, explained it: לֹא שָׁנִיתִי - I did not strike a nation and repeat a blow to it; but as for you, I have kept you up after much punishment, and My arrows are ended, but you are not ended.

Will a man rob Our Sages explained this as an expression of robbery, and it is an Aramaism.
With tithes and with the terumah levy The tithes and the terumah - levy that you steal from the priests and the Levites is tantamount to robbing Me.

You are cursed with a curse because of this iniquity, for which I send a curse into the work of your hands; but nevertheless, you rob Me.

so that there may be nourishment in My House There shall be food accessible for My servants.

And I will rebuke the devourer for your sake The finishing locusts and the shearing locusts, which devour the grain of your field and your vines.

“It is futile to serve God” We worship Him for nothing, for we will receive no reward.
in anxious worry with low spirits.

And now we praise the bold transgressors, etc. We worshipped Him and kept His charge, but now we see that the wicked are prospering - to the extent that we praise them for the wicked deeds.
Yea, they tempt God, saying, “Let us see what He will be able to do to us.” and they have, nevertheless, escaped harm, and they have not stumbled.

Then the God-fearing men spoke, etc. I retort upon your words then, when the wicked commit evil and the good go about in anxious worry because of Me. The God-fearing men spoke to one another not to adopt their evil deeds; and, as for Me, their words are not forgotten to Me. And although I do not hasten to visit retribution, I have hearkened and heard, and I have commanded that a book of remembrance be written for them. Their words shall be preserved for Me.

for that day when I make a treasure that I have stored and put away, with which to pay My reward. There I will show you what the difference is between a righteous man and a wicked man.
a treasure a treasure; estouj, estui in Old French.
