Job 34:3

For the ear trieth words - Ascertains their meaning, and especially determines what words are worth regarding. The object of this is, to fix the attention on what he was about to say; to get the ear so that every word should make its proper impression. The word ear in this place, however, seems not to be used to denote the external organ, but the whole faculty of hearing. It is by hearing that the meaning of what is said is determined, as it is by the taste that the quality of food is discerned.

As the mouth tasteth meat - Margin, as in Hebrew “palate.” The meaning is, as the organ of taste determines the nature of the various articles of food. The same figure is used by Job in Job 12:11.
