Deuteronomy 4:10

יום אשר עמדת THE DAY THAT THOU STOODEST — This is to be connected with the preceding verse thus: [The things] which thine eyes saw … on the day that thou stoodest … at Horeb, — where thou didst perceive the thunder and lightning. יִלְמְדוּן — The Targum is יֵלְפוּן, “They shall learn" (more lit., the action reverts to themselves), while — יְלַמֵּדוּן the Targum is יְאַלְפוּן, “They shall teach" (more lit., the action reverts to others).

the day that thou stoodest before the Lord thy God in Ḥorev, when the Lord said to me, Gather me the people together, and I will make them hear my words, that they may learn to fear me all the days that they shall live upon the earth, and that they may teach their children.

י֗וֹם אֲשֶׁ֨ר עָמַ֜דְתָּ לִפְנֵ֨י יְהֹוָ֣ה אֱלֹהֶ֘יךָ֮ בְּחֹרֵב֒ בֶּאֱמֹ֨ר יְהֹוָ֜ה אֵלַ֗י הַקְהֶל־לִי֙ אֶת־הָעָ֔ם וְאַשְׁמִעֵ֖ם אֶת־דְּבָרָ֑י אֲשֶׁ֨ר יִלְמְד֜וּן לְיִרְאָ֣ה אֹתִ֗י כׇּל־הַיָּמִים֙ אֲשֶׁ֨ר הֵ֤ם חַיִּים֙ עַל־הָ֣אֲדָמָ֔ה וְאֶת־בְּנֵיהֶ֖ם יְלַמֵּדֽוּן׃
