Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it is his portion.

a man to whom God has given riches and wealth and honor so that his soul lacks nothing of all that he desires; yet God has not empowered him to eat from them, for a foreigner enjoys them. This is vanity and a severe affliction.
