Didymus the Blind : This is the literal interpretation. If someone has much money, if he has lots of good food and many wines, he still cannot eat and drink all of it. But he doubtless has a gift: whatever he can consume, if he has enough food to satisfy him and enough drink, this is a gift from God. But when someone eats and drinks more than necessary, then it is not a gift from God but a gift from desire.Regarding the spiritual interpretation: God gives wisdom along with the riches and capabilities inherent in wisdom, that is, wisdom's insights, so that people eat and drink from the things they have received: the bread of wisdom, its water, the wine, which he mingled into a cup. This is a gift from God. If one takes the spiritual in the right way, it is, finally, the grace of his lot. — COMMENTARY ON Ecclesiastes 164:1
