'Hand' in the Bible

For a man may do his work with wisdom, knowledge, and skill; however, he must hand over the fruit of his labor as an inheritance to someone else who did not work for it. This also is futile, and an awful injustice!

Just as he came forth from his mother's womb, naked will he return as he came, and he will take nothing in his hand that he may carry away from his toil.

So I reflected on all this, attempting to clear it all up. I concluded that the righteous and the wise, as well as their works, are in the hand of God; whether a person will be loved or hated -- no one knows what lies ahead.
