Parallel
Exodus 8:15
Berean Standard Bible · Westminster Leningrad Codex
When Pharaoh saw that there was relief, however, he hardened (note: Or made heavy; also in verse 32) his heart and would not listen to Moses and Aaron, just as the LORD had said.
וַיַּ֣רְא פַּרְעֹ֗ה כִּ֤י הָֽיְתָה֙ הָֽרְוָחָ֔ה וְהַכְבֵּד֙ אֶת־ לִבּ֔וֹ וְלֹ֥א שָׁמַ֖ע אֲלֵהֶ֑ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה׃ס
