וַיְחַזֵּ֤ק יְהוָה֙ אֶת־לֵ֣ב פַּרְעֹ֔ה וְלֹ֥א שָׁמַ֖ע אֲלֵהֶ֑ם כַּאֲשֶׁ֛ר דִּבֶּ֥ר יְהוָ֖ה אֶל־מֹשֶֽׁה׃ (ס)
И ожесточил Господь сердце фараона, и не послушал их; как говорил Господь Моисею.
Targum Jonathan
And the Lord hardened the design of Pharoh's heart, and he would not hearken to them, as the Lord had said to Mosheh.
