כָּֽל־הַגּוֹיִ֞ם נִקְבְּצ֣וּ יַחְדָּ֗ו וְיֵאָֽסְפוּ֙ לְאֻמִּ֔ים מִ֤י בָהֶם֙ יַגִּ֣יד זֹ֔את וְרִֽאשֹׁנ֖וֹת יַשְׁמִיעֻ֑נוּ יִתְּנ֤וּ עֵֽדֵיהֶם֙ וְיִצְדָּ֔קוּ וְיִשְׁמְע֖וּ וְיֹאמְר֥וּ אֱמֶֽת׃
Congréguense á una todas las gentes, y júntense todos los pueblos: ¿quién de ellos hay que nos dé nuevas de esto, y que nos haga oir las cosas primeras? Presenten sus testigos, y justifíquense; oigan, y digan: Verdad.
Rashi
When you find my beloved. In the future, on the Day of Judgement, when it will be requested of you to testify about me, as the matter is stated, “Let them present their witnesses, and they will be vindicated.”35Yeshayahu 43:9. See Maseches Avodah Zarah 3a.
Rabbeinu Bahya
This is what the Talmud alluded to at the beginning of Avodah Zarah (folio 2) when it says that in the future G’d would bring a Torah scroll and deposit it in His lap and say: “Is there anyone amongst you who can tell Me זאת? [a reference to Isaiah 43,9 where the Torah is referred to as זאת. Ed.] Upon hearing this all the citizens realized that they had been found out. They left the proximity of the Lord in fear of their lives.
