Exodus 19:3

ומשה עלה AND MOSES WENT UP on the second day of the month (Mekhilta); for all his ascents to the mountain were made early in the morning, as it is stated (Exodus 34:4) “And Moses rose up early in the morning [and went up unto mount Sinai]” (Shabbat 86b). כה תאמר THUS SHALT THOU SAY — Thus, i. e. in this (the Hebrew) language (cf. Mekhilta) and in this form of words. לבית יעקב TO THE HOUSE OF JACOB — This denotes the women — to them you shall speak in gentle language (Mekhilta). ותגיד לבני ישראל AND TELL THE CHILDREN (lit., the sons) OF ISRAEL — explain to the men the punishments and the details of the commandments in words that are as hard (distasteful) as wormwood (גידין) (cf. Shabbat 87a; Midrash לקח טוב‎).

וּמֹשֶׁ֥ה עָלָ֖ה אֶל־הָאֱלֹהִ֑ים וַיִּקְרָ֨א אֵלָ֤יו יְהֹוָה֙ מִן־הָהָ֣ר לֵאמֹ֔ר כֹּ֤ה תֹאמַר֙ לְבֵ֣ית יַעֲקֹ֔ב וְתַגֵּ֖יד לִבְנֵ֥י יִשְׂרָאֵֽל׃

And Moshe went up to God, and the Lord called to him out of the mountain, saying, Thus shalt thou say to the house of Ya῾aqov, and tell the children of Yisra᾽el;
