'Part' in the Bible

Lo, truth Thou hast desired in the inward parts, And in the hidden part Wisdom Thou causest me to know.

They search out perverse things, 'We perfected a searching search,' And the inward part of man, and the heart are deep.

I take the wings of morning, I dwell in the uttermost part of the sea,

My substance was not hid from Thee, When I was made in secret, Curiously wrought in the lower part of earth.
