SEV Biblia, Chapter 7:3
Y yo endureceré el corazón del Faraón, y multiplicaré en la tierra de Egipto mis señales y mis maravillas.
Clarke's Bible Commentary - Exodus 7:3
Verse 3. I will harden Pharaoh's heart] I will permit his stubbornness and obstinacy still to remain, that I may have the greater opportunity to multiply my wonders in the land, that the Egyptians may know that I only am Jehovah, the self- existent God. See note on "chap. iv. 21".
Matthew Henry Commentary
Verses 1-7 - God glorifies himself. He makes people know that he is Jehovah. Israe is made to know it by the performance of his promises to them, and the Egyptians by the pouring out of his wrath upon them. Moses, as the ambassador of Jehovah, speaking in his name, laid commands upo Pharaoh, denounced threatenings against him, and called for judgment upon him. Pharaoh, proud and great as he was, could not resist. Mose stood not in awe of Pharaoh, but made him tremble. This seems to be meant in the words, Thou shalt be a god unto Pharaoh. At length Mose is delivered from his fears. He makes no more objections, but, being strengthened in faith, goes about his work with courage, and proceed in it with perseverance.
