'Undismayed' in the Bible

Then Moses said to the people, “Do not be afraid! Take your stand [be firm and confident and undismayed] and see the salvation of the Lord which He will accomplish for you today; for those Egyptians whom you have seen today, you will never see again.

By faith he left Egypt, being unafraid of the wrath of the king; for he endured [steadfastly], as seeing Him who is unseen.
