Ezekiel 15:3 - Coke's Commentary on the Holy Bible

Shall wood be taken thereof— It is observable, that the wood of the vine is of no use in building, or in making any piece of furniture or domestic utensil. Bishop Lowth observes, that it is the chief excellence of a parable to consist of an image which is known and proper to the subject, and whose end is plain and determined by custom; the necessary consequence of which is perspicuity, wherein the chief beauty of an allegory consists. The prophets frequently make use of this kind of images, by way of comparison or illustration; and this of the useless vine, by which these ungrateful people are more than once described, is an image of this sort. See his 10th Prelection.
