God can give a sign that is no wonder, for example, Exodus 3:12 where the sign is fulfilled by natural
means, that is, a walking people (Israel walking out of Egypt as a sign). A wonder is a supernatural event or manifestation of divine power (e.g., Exodus 4:8. God gives a preview
to Moses of the wonders (plagues) of Egypt (Exodus 7:1 – 11:10).
20 J'étendrai ma main, et je frapperai l'Egypte par toutes sortes de prodiges que je ferai au milieu d'elle. Après quoi, il vous laissera aller.
