'Hidden' in the Bible

'And also the locust doth Jehovah thy God send among them, till the destruction of those who are left, and of those who are hidden from thy presence;

'Thou dost not see the ox of thy brother or his sheep driven away, and hast hidden thyself from them, thou dost certainly turn them back to thy brother;

The things hidden are to Jehovah our God, and the things revealed are to us and to our sons -- to the age, to do all the words of this law.

and Mine anger hath burned against it in that day, and I have forsaken them, and hidden My face from them, and it hath been for consumption, and many evils and distresses have found it, and it hath said in that day, Is it not because that my God is not in my midst -- these evils have found me?

Peoples to the mountain they call, There they sacrifice righteous sacrifices; For the abundance of the seas they suck, And hidden things hidden in the sand.
