'Secure' in the Bible

But you are to take a few strands from the hair and secure them in the folds of your robe.

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!”

The trees of the field will give their fruit, and the land will yield its produce; My flock will be secure in their land. They will know that I am Yahweh when I break the bars of their yoke and rescue them from the hands of those who enslave them.

I'll make a secure covenant with them, one that will last forever. I will establish them, make them increase in population, and will place my sanctuary in their midst forever.
