'Appetite' in the Bible

Wilt thou hunt the prey for the lion? or fill the appetite of the young lions,

And put a knife to thy throat, if thou be a man given to appetite.

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

It shall even be as when an hungry man dreameth, and, behold, he eateth; but he awaketh, and his soul is empty: or as when a thirsty man dreameth, and, behold, he drinketh; but he awaketh, and, behold, he is faint, and his soul hath appetite: so shall the multitude of all the nations be, that fight against mount Zion.
