15:1–24:14 This section contains a series of eight metaphors, each reiterating from a different angle the certainty of Jerusalem’s forthcoming judgment. The images are of a worthless vine (ch 15); a faithless wife (ch 16); a vine and two eagles (ch 17); sour grapes (ch 18); a lion and her cubs (ch 19); a sword (ch 21); two degenerate sisters (ch 23); and a cooking pot (ch 24). 15:1-5 The wood of a tree can be used to make all kinds of useful objects, pegs being the simplest and most basic. A vine’s wood, however, has no strength, size, or beauty, so it is useless for pegs and it is not even good as fuel because it burns too quickly. It is completely useless.
