'Hand of God' in the Bible

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

For all this I laid to my heart and indeed to investigate all this, that the righteous, and the wise, and their works, are in the hand of God; man knoweth neither love nor hatred: all is before them.
