‘For though the fig tree will not blossom,
Nor will fruit be in the vines,
The produce of the olive will fail,
And the fields will yield no food,
The flock will be cut off from the fold,
And there will be no herd in the stalls,
Yet will I rejoice in YHWH,
I will joy in the God of my salvation.'
Habakkuk has won through to triumphant faith. He declare that although everything goes wrong around him, and invasion destroys all the necessities of life, and leaves them barren of food apart from what they have stored up, which will disappear in the siege, he will rejoice in YHWH, and joy in the God of his salvation.
Here salvation refers not to deliverance, but to inner peace, deliverance within himself, something that externals cannot touch. For he will find rest in the midst of tribulation, and peace of heart with his God.
