'Desirable' in the Bible

Is there in my tongue perverseness? Discerneth not my palate desirable things?

“Does the ear not put words to the test,Just as the palate tastes its food [distinguishing between the desirable and the undesirable]?

For he hath not known ease in his belly. With his desirable thing he delivereth not himself.

And his life hath nauseated bread, And his soul desirable food.
