Hebrew translation:

164. בֹּא רְאֵה, יִצְחָק צְחוֹק, חֶדְוָה שֶׁמַּחֲלִיפָה מַיִם בְּאֵשׁ וְאֵשׁ בְּמַיִם, וְעַל זֶה נִקְרָא כָּךְ. וְלָכֵן הַקָּדוֹשׁ בָּרוּךְ הוּא קָרָא לוֹ כָּךְ בְּטֶרֶם יָצָא לָעוֹלָם בְּשֵׁם זֶה וְהוֹדִיעַ לְאַבְרָהָם.
165. וּבֹא וּרְאֵה, בְּכָל הָאֲחֵרִים הִשְׁאִיר לָהֶם הַקָּדוֹשׁ בָּרוּךְ הוּא לִקְרֹא לָהֶם שֵׁמוֹת, וַאֲפִלּוּ נָשִׁים הָיוּ קוֹרְאוֹת לִבְנֵיהֶן שֵׁמוֹת, אֲבָל כָּאן לֹא הִשְׁאִיר הַקָּדוֹשׁ בָּרוּךְ הוּא לְאִמּוֹ לִקְרֹא לוֹ שֵׁם, אֶלָּא לְאַבְרָהָם, שֶׁכָּתוּב וְקָרָאתָ אֶת שְׁמוֹ יִצְחָק. אַתָּה וְלֹא אַחֵר. כְּדֵי לְהַחֲלִיף מַיִם בְּאֵשׁ וְאֵשׁ בְּמַיִם לְהַכְלִילוֹ בְּצִדּוֹ.
166. כֵּיוָן שֶׁהִתְבַּשֵּׂר אַבְרָהָם בְּיִצְחָק, מַה כָּתוּב? וַיָּקֻמוּ מִשָּׁם הָאֲנָשִׁים וַיַּשְׁקִפוּ עַל פְּנֵי סְדֹם. רַבִּי אֶלְעָזָר אָמַר, בֹּא רְאֵה כַּמָּה נוֹהֵג הַקָּדוֹשׁ בָּרוּךְ הוּא טוֹבָה עִם כָּל הַבְּרִיּוֹת, וְכָל שֶׁכֵּן לְאוֹתָם שֶׁהוֹלְכִים בִּדְרָכָיו, שֶׁאֲפִלּוּ בִּזְמַן שֶׁרוֹצֶה לָדוּן אֶת הָעוֹלָם, הוּא גוֹרֵם לְמִי שֶׁאוֹהֵב אוֹתוֹ לִזְכּוֹת בַּדָּבָר עַד שֶׁלֹּא יָבֹא אוֹתוֹ הַדִּין לָעוֹלָם.


Zohar Vayera
Continued from previous DZ
Isaac is joy and happiness because he replaced water with fire and fire with water, meaning that the Left and Right are included. Because he is the aspect of Left, which is fire, and included in the water, which is the Right and Chessed, as explained above, joy and happiness are drawn from the Left. For this reason, the Holy One, Blessed be He, called him with the name Yitzchak (Isaac) and told Abraham, even before he came out into the world.

Except for Isaac, the Holy One, Blessed be He, allowed the others to name names, and even women would name their sons, but here God did not allow his mother to name him, but Abraham, as it is written, “וְקָרָאתָ אֶת שְׁמוֹ יִצְחָק” “and you shall call his name Isaac,” you and no one else. To replace water with fire and fire with water, to integrate the Left with the Right and the Right with the Left as above, and to include Isaac on the Right of Abraham, meaning that he was affected by Chessed called water and Right. Isaac received the illumination of the Left, which is the secret of fire. They were included in each other, and by this merger, the name Yitzchak was given. The Holy One, Blessed be He, told the name to Abraham so he would make the connection described above, in which he became the source of joy and laughter as above.

After Abraham was told about Isaac, it is written;
Genesis 18:16
“וַיָּקֻמוּ מִשָּׁם הָאֲנָשִׁים וַיַּשְׁקִפוּ עַל פְּנֵי סְדֹם וְאַבְרָהָם הֹלֵךְ עִמָּם לְשַׁלְּחָם.”
“Then the men rose from there and looked toward Sodom, and Abraham went with them to send them on the way.”
Rabbi Elazar said, we see how much the Holy One, Blessed be He, govern all people with the measure of his goodness, and even more so to those who walk in his ways, that even when he wants to bring judgment to the world, he makes good things to happen to those he loves, giving them gifts before his judgment manifest.

The ‘men’ are the angels that came to destroy Sodom and Gemora but first came to bring the good message to Abraham. He walked with them, listening to the plan for the sin cities.
The spiritual principle that we study in the following Zohar paragraphs is that Hashem reveals to the Tzadikim judgments that are about to happen in the world. The other side that executes the judgments can only act after their actions are shown to the Tzadikim through messages that most people cannot see.
