וַיִּקְרָ֥א מֹשֶׁ֛ה אֶל־כָּל־יִשְׂרָאֵ֖ל וַיֹּ֣אמֶר אֲלֵהֶ֑ם אַתֶּ֣ם רְאִיתֶ֗ם אֵ֣ת כָּל־אֲשֶׁר֩ עָשָׂ֨ה יְהוָ֤ה לְעֵֽינֵיכֶם֙ בְּאֶ֣רֶץ מִצְרַ֔יִם לְפַרְעֹ֥ה וּלְכָל־עֲבָדָ֖יו וּלְכָל־אַרְצֽוֹ׃
摩西召集全以色列，對他們說：「你們親眼看見永恆者在埃及地對法老、對他所有的臣僕、對他全國所行的一切，
Ibn Ezra
Moshe summoned all Israel for the purpose of ratifying the covenant. Accordingly, this passage is immediately followed by the passage “You are standing assembled today…” [: 9].
Ramban
AND MOSES CALLED ALL ISRAEL. The purport thereof is that after he finished telling them the words of the covenant he called them again, saying, “Hear, O Israel, Ye have seen etc.,” for they had not left him, since these sections are all connected.
Or HaChaim
ויקרא משה אל כל ישראל, Moses called out to the entire Jewish people, etc. Even though Moses had been addressing the whole Jewish people up until now also, he gathered the women and the children as well as the proselytes to prepare them for renewed acceptance of the covenant which is the subject of Parshat Nitzavim.
