וְעַתָּ֣ה לְכָ֔ה וְאֶֽשְׁלָחֲךָ֖ אֶל־פַּרְעֹ֑ה וְהוֹצֵ֛א אֶת־עַמִּ֥י בְנֵֽי־יִשְׂרָאֵ֖ל מִמִּצְרָֽיִם׃
Rashi on Exodus
ועתה לך ואשלחך אל פרעה COME NOW, THEREFORE, AND I WILL SEND THEE UNTO PHARAOH — And if you ask “What will this avail?” והוצא את עמי AND BRING FORTH MY PEOPLE — your words will prove effective and you will bring them forth from there.
Rashbam on Exodus
והוצא את עמי בני ישראל ממצרים, as a result of what you will tell Pharaoh in My name.
Sforno on Exodus
ועתה לכה ואשלחך, to them, to warn them before I have to resort to punishing them.
