"And Moses went up to God"—this was the first and second day. "And the LORD called to him"—this teaches that calling preceded speech. "Thus [koh]"—in the holy tongue. "Thus"—in this order. "Thus"—concerning this matter. "Thus"—neither diminishing nor adding. "Thus you shall say to the house of Jacob"—these are the women; "and tell the children of Israel"—these are the men.
The Call Before the Word and Thus Say to the House of Jacob
Yalkut Shimoni on Torah 276:2
וּמשֶׁה עָלָה אֶל הָאֱלֹהִים, זֶה יוֹם רִאשׁוֹן וְשֵׁנִי. וַיִּקְרָא אֵלָיו, מַגִּיד שֶׁקְּרִיאָה קָדְמָה לְדִבּוּר. כֹּה בִּלְשׁוֹן הַקֹּדֶשׁ. כֹּה בַּסֵּדֶר הַזֶּה. כֹּה בְּעִנְיָן זֶה. כֹּה שֶׁלֹּא תִּפְחוֹת וְלֹא תּוֹסִיף. כֹּה תֹאמַר לְבֵית יַעֲקֹב, אֵלּוּ הַנָּשִׁים וְתַגֵּיד לִבְנֵי יִשְׂרָאֵל אֵלּוּ הָאֲנָשִׁים.
