'Secure' in the Bible

On that day messengers will go forth from Me in ships to frighten secure Ethiopia; and anguish will be on them as on the day of Egypt; for behold, it comes!”

Also the tree of the field will yield its fruit and the earth will yield its increase, and they will be secure on their land. Then they will know that I am the Lord, when I have broken the bars of their yoke and have delivered them from the hand of those who enslaved them.
