Albert Barnes Commentary Jeremiah 8:20

"The harvest is past, the summer is ended, and we are not saved." — Jeremiah 8:20 (ASV)

The summer - Rather, the fruit-gathering, which follows the grain-harvest. The grain has failed; the fruit-gathering has also proved unproductive; so despair seized the people when they saw opportunities for their deliverance again and again pass by, until God seemed utterly to have forgotten them.
