'Appetite' in the Bible

I have sought in my heart to draw out with wine my appetite, (and my heart leading in wisdom), and to take hold on folly till that I see where is this -- the good to the sons of man of that which they do under the heavens, the number of the days of their lives.

All the labour of man is for his mouth, and yet the appetite is not filled.

Furthermore, they are afraid of a high place and of dangers on the road; the almond tree (hair) blossoms [white], and the grasshopper (a little thing) is a burden, and the caperberry (desire, appetite) fails. For man goes to his eternal home and the mourners go about the streets and market places.
