“Pharaoh also called for the wise men and the sorcerers; and they too, the magicians of Egypt, did so with their spells” (Exodus 7:11). “Pharaoh also called for the wise men and the sorcerers.” At that moment, Pharaoh began laughing at them and clucking at them like a hen, saying to them: ‘Are these the signs of your God? The way of the world is that people bring merchandise to a place that needs it.
Do they bring fish brine to Spain, fish to Akko? Do you not know that all sorcery is in my control?’ Immediately, he sent and brought children from their schools, and they too performed this [wonder]. Moreover, he called his wife and she did so, as it is stated: “Pharaoh also [gam] called.”
What is gam? It is that he called even his wife and she did so. “They too [gam], the magicians of Egypt, did so.” What is gam? It is that he called even four- and five-year-old children, and they did so.
