Parallel
Exodus 7:13
Berean Standard Bible · Westminster Leningrad Codex
Still, Pharaoh’s heart was hardened (note: Or stiffened or strengthened; also in verse 22), and he would not listen to them, just as the LORD had said.
וַיֶּחֱזַק֙ לֵ֣ב פַּרְעֹ֔ה וְלֹ֥א שָׁמַ֖ע אֲלֵהֶ֑ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה׃פ
