What was the First miracle Moses performed?

Exodus ch.3 relates how God appeared to Moses in the Burning Bush, and the bush, though on fire, was not consumed. Other miracles (such as the rod, and the Plagues) were later.Earlier events, such as Moses in the Nile and being rescued by Pharaoh's daughter and later fleeing from Pharaoh (Exodus ch.2), were not stated as having been open miracles.

According to Jewish tradition (and not stated openly in the Torah), Moses was able to escape Pharaoh's executioners (Exodus 2:15) only through a miracle (Rashi commentary on Exodus 4:11).
