'Hidden' in the Bible

To those who are longing for death even though it does not come? To those who search for it more than for hidden treasure?

But you've hidden these things in your heart I know this was your purpose:

He uncovers the hidden dimensions from darkness, bringing what is in deep shadow to light.

A rope lies hidden in the dirt; a trap lies waiting for him where he is walking."

He dams up flowing rivers, bringing hidden things to light."

It has been concealed from the sight of every living creature and hidden even from the birds in the skies.
