'Work of God' in the Bible

Consider the work of God, - for who can straighten what he hath bent?

Then I considered all the work of God, that man could not find out the work that was done under the sun, inasmuch as man toileth in seeking and yet cannot find, - yea, even though the wise man should say he knoweth, yet can he not find it out.

Just as thou knowest not what is the way of the spirit, when the body is in the womb of her that is with child, even, so, canst thou not know the work of God, who maketh all.
