The harvest is past, etc. For "summer," read fruit-gathering. The people again becomes the speaker. The form of the speech reminds one of a proverb. When the harvest was over and the fruit-gathering ended, the husbandmen looked for a quiet time of refreshment.
Judah had had its "harvest-time" and then its "fruit-gathering;" its needs had been gradually, increasing, and, on the analogy of previous deliverances (comp. Isaiah 18:4; Isaiah 33:10), it might have been expected that God would have interposed, his help being only delayed in order to be the more signally supernatural.
But we are not saved (or rather, delivered).
