SEV Biblia, Chapter 7:5
Y sabrán los egipcios que yo soy el SEÑOR, cuando extendiere mi mano sobre Egipto, y sacare los hijos de Israel de en medio de ellos.
Clarke's Bible Commentary - Exodus 7:5
Verse 5. And bring out the children of Israel] Pharaoh's obstinacy was either caused or permitted in mercy to the Egyptians, that he and his magicians being suffered to oppose Moses and Aaron to the uttermost of their power, the Israelites might be brought out of Egypt in so signal a manner, in spite of all the opposition of the Egyptians, their king, and their gods, that Jehovah might appear to be All-mighty and All-sufficient.
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.
