They shewed his signs among them - literally, “They placed among them the words of his signs.” So the margin. The reference is to the miracles performed in Egypt in bringing calamities upon the Egyptians to induce them to permit the children of Israel to go out from their bondage. They were the agents in setting these wonders before the Egyptians. The term words is employed here - “the words of his signs” - to keep up the idea that it was by the command of God that this was done, or by his word. It was by no power of their own, but only by the authority of God.
And wonders in the land of Ham - Miracles. Things suited to produce astonishment. See Psalms 105:5.
