'Hand of God' in the Bible

There is nothing better for a man than that he should eat and drink, and make his soul enjoy good in his labor. This also I saw, that it is from the hand of God.

For all this I laid to my heart, even to explore all this: that the righteous, and the wise, and their works, are in the hand of God; whether it is love or hatred, man doesn't know it; all is before them.
