(א) בָּרוּךְ אַתָּה יְהֹוָה אֱלֹהֵֽינוּ מֶֽלֶךְ הָעוֹלָם אֲשֶׁר קִדְּ֒שָֽׁנוּ בְּמִצְוֹתָיו וְצִוָּנוּ לַעֲסֹק בְּדִבְרֵי תוֹרָה:
(1) Blessed are You, Adonoy our God, Ruler of the Universe, Who sanctified us with commandments and commanded us to be engrossed in the words of Torah.
(13) So Hashem spoke to both Moses and Aaron in regard to the Israelites and Pharaoh king of Egypt, instructing them to deliver the Israelites from the land of Egypt.
Nehama Leibowitz, "New Studies in Shemot" (book)
Not only Pharaoh had to be persuaded to let the children of Israel go but Moses and Aaron had to persuade the children of Israel to leave Egypt, to willingly accept freedom with all its responsibilities and submit to the yoke of Heaven, rejecting the easier course of being ruled by others.
