Isaiah 5:24 (b) GOD is thus informing Israel that there would be no blessing waiting for them in future days. The fact that there were no flowers indicated that there would be no fruit.
Isaiah 27:6 (b) The restoration of Israel is to be a slow process as in the formation of fruit. First, there is the bud, then the bloom, and then the fruit.
Ezekiel 7:10 (b) As the blossom is an evidence of future fruitfulness, so on a rod it indicates the coming of GOD's punishment on His people. It presages fruit. In this case it is foretelling that the fruit will be of the kind that hurts and harms Israel.
Habakkuk 3:17 (b) Flowers always indicate that fruit is to follow.
Flowers raise the hope of the farmer for a bountiful crop. In this case since there were no flowers it would indicate clearly that there would be no future fruit, but rather famine and sorrow. Even though this was the case, the prophet would rejoice and sing.
