Ezekiel 15:1-3

‘And the word of Yahweh came to me saying, “Son of man, what is the vine tree more than any tree, the vine branch which is among the trees of the forest? Will wood be taken from it to make any work? Or will men take a pin of it to hang any vessel on it?” '

The later implication is that Jerusalem is like the vine (Ezekiel 15:5), but in Ezekiel's case it is the wild vine, one of the trees of the forest. Unlike other trees in the forest its usefulness is limited to bearing its fruit. But who gathers fruit from the wild vine? And apart from this it is nothing. It is useless for being carved or shaped, it is useless as a pin to hang things on. If it does not bear fruit it is nothing. The pin is elsewhere used to indicate someone who can be relied on (Isaiah 22:23; Zechariah 10:4). But Jerusalem is like a wild vine, not to be depended on. No one partakes of its fruit and it is useless for anything else. It should of course be a fruitful vine but it is not, for it has placed itself as one among the nations in their idolatry.

In the past Israel was likened to a vine that should have been fruitful, but sadly revealed itself as a wild vine (see Genesis 49:22; Deuteronomy 32:32; Psalms 80:8; Isaiah 5:1; Jeremiah 2:21; Hosea 10:1). This is the end of the process.
