I'm not sure which version of The Bible you are reading, but in other versions, the verse reads like this:
21 And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go. (KJV)
the word "power" you are talking about is translated in the kjv as "which I have put in thine hand"
The NLT says "which I have empowered you"...
I'm not sure exactly which word it is in the greek. I hope this helps
