'Hidden' in the Bible

Or why was I not hidden like a miscarried child,like infants who never see daylight?

who wait for death, but it does not come,and search for it more than for hidden treasure,

Why is life given to a man whose path is hidden,whom God has hedged in?

“Yet You concealed these thoughts in Your heart;I know that this was Your hidden plan:

A rope lies hidden for him on the ground,and a snare waits for him along the path.

He dams up the streams from flowingso that he may bring to light what is hidden.

It is hidden from the eyes of every living thingand concealed from the birds of the sky.
