'Hidden' in the Bible

Who can discern his errors? Clear thou me from hidden faults .

Behold, thou desirest truth in the inward parts; And in the hidden part thou wilt make me to know wisdom.

Thy take crafty counsel against thy people, And consult together against thy hidden ones.

My frame was not hidden from thee, When I was made in secret, And curiously wrought in the lowest parts of the earth.

When my spirit was overwhelmed within me, Thou knewest my path. In the way wherein I walk Have they hidden a snare for me.
