The whole chapter is here, a verse to a line.
וַיְהִי דְבַר־יְהוָה אֵלַי לֵאמֹֽר׃
Moreover the word of the LORD came unto me, saying:
בֶּן־אָדָם שִׂים פָּנֶיךָ עַל־הַר שֵׂעִיר וְהִנָּבֵא עָלָֽיו׃
’Son of man, set thy face against mount Seir, and prophesy against it,
וְאָמַרְתָּ לּוֹ כֹּה אָמַר אֲדֹנָי יְהוִה הִנְנִי אֵלֶיךָ הַר־שֵׂעִיר וְנָטִיתִי יָדִי עָלֶיךָ וּנְתַתִּיךָ שְׁמָמָה וּמְשַׁמָּֽה׃
and say unto it: Thus saith the Lord GOD: Behold, I am against thee, O mount Seir, and I will stretch out My hand against thee, and I will make thee most desolate.
עָרֶיךָ חָרְבָּה אָשִׂים וְאַתָּה שְׁמָמָה תִהְיֶה וְיָדַעְתָּ כִּי־אֲנִי יְהוָֽה׃
I will lay thy cities waste, and thou shalt be desolate; and thou shalt know that I am the LORD.
יַעַן הֱיוֹת לְךָ אֵיבַת עוֹלָם וַתַּגֵּר אֶת־בְּנֵי־יִשְׂרָאֵל עַל־יְדֵי־חָרֶב בְּעֵת אֵידָם בְּעֵת עֲוֺן קֵֽץ׃
Because thou hast had a hatred of old, and hast hurled the children of Israel unto the power of the sword in the time of their calamity, in the time of the iniquity of the end;
לָכֵן חַי־אָנִי נְאֻם אֲדֹנָי יְהוִה כִּי־לְדָם אֶעֶשְׂךָ וְדָם יִרְדֲּפֶךָ אִם־לֹא דָם שָׂנֵאתָ וְדָם יִרְדֲּפֶֽךָ׃
therefore, as I live, saith the Lord GOD, I will prepare thee unto blood, and blood shall pursue thee; surely thou hast hated thine own blood, therefore blood shall pursue thee.
וְנָתַתִּי אֶת־הַר שֵׂעִיר לְשִׁמְמָה וּשְׁמָמָה וְהִכְרַתִּי מִמֶּנּוּ עֹבֵר וָשָֽׁב׃
Thus will I make mount Seir most desolate, and cut off from it him that passeth through and him that returneth.
וּמִלֵּאתִי אֶת־הָרָיו חֲלָלָיו גִּבְעוֹתֶיךָ וְגֵאוֹתֶיךָ וְכָל־אֲפִיקֶיךָ חַלְלֵי־חֶרֶב יִפְּלוּ בָהֶֽם׃
And I will fill his mountains with his slain; in thy hills and in thy valleys and in all thy streams shall they fall that are slain with the sword.
שִׁמְמוֹת עוֹלָם אֶתֶּנְךָ וְעָרֶיךָ לֹא תָשֹׁבְנָה וִידַעְתֶּם כִּי־אֲנִי יְהוָֽה׃
I will make thee perpetual desolations, and thy cities shall not return; and ye shall know that I am the LORD.
יַעַן אֲמָרְךָ אֶת־שְׁנֵי הַגּוֹיִם וְאֶת־שְׁתֵּי הָאֲרָצוֹת לִי תִהְיֶינָה וִירַשְׁנוּהָ וַיהוָה שָׁם הָיָֽה׃
Because thou hast said: These two nations and these two countries shall be mine, and we will possess it; whereas the LORD was there;
לָכֵן חַי־אָנִי נְאֻם אֲדֹנָי יְהוִה וְעָשִׂיתִי כְּאַפְּךָ וּכְקִנְאָתְךָ אֲשֶׁר עָשִׂיתָה מִשִּׂנְאָתֶיךָ בָּם וְנוֹדַעְתִּי בָם כַּאֲשֶׁר אֶשְׁפְּטֶֽךָ׃
therefore, as I live, saith the Lord GOD, I will do according to thine anger and according to thine envy, which thou hast used out of thy hatred against them; and I will make Myself known among them, when I shall judge thee.
וְיָדַעְתָּ כִּי־אֲנִי יְהוָה שָׁמַעְתִּי אֶת־כָּל־נָאָצוֹתֶיךָ אֲשֶׁר אָמַרְתָּ עַל־הָרֵי יִשְׂרָאֵל לֵאמֹר שָׁמֵמוּ לָנוּ נִתְּנוּ לְאָכְלָֽה׃
And thou shalt know that I the LORD have heard all thy blasphemies which thou hast spoken against the mountains of Israel, saying: They are laid desolate, they are given us to devour.
וַתַּגְדִּילוּ עָלַי בְּפִיכֶם וְהַעְתַּרְתֶּם עָלַי דִּבְרֵיכֶם אֲנִי שָׁמָֽעְתִּי׃
And ye have magnified yourselves against Me with your mouth, and have multiplied your words against Me; I have heard it.
כֹּה אָמַר אֲדֹנָי יְהוִה כִּשְׂמֹחַ כָּל־הָאָרֶץ שְׁמָמָה אֶעֱשֶׂה־לָּֽךְ׃
Thus saith the Lord GOD: When the whole earth rejoiceth, I will make thee desolate.
כְּשִׂמְחָתְךָ לְנַחְלַת בֵּית־יִשְׂרָאֵל עַל אֲשֶׁר־שָׁמֵמָה כֵּן אֶעֱשֶׂה־לָּךְ שְׁמָמָה תִהְיֶה הַר־שֵׂעִיר וְכָל־אֱדוֹם כֻּלָּהּ וְיָדְעוּ כִּי־אֲנִי יְהוָֽה׃
As thou didst rejoice over the inheritance of the house of Israel, because it was desolate, so will I do unto thee; thou shalt be desolate, O mount Seir, and all Edom, even all of it; and they shall know that I am the LORD.
