The {p} harvest is past, the summer is ended, and we are not saved.

(p) The people wonder that they have for so long a time looked for comfort in vain.

Jamieson-Fausset-Brown Bible Commentary

20. Proverbial. Meaning: One season of hope after another has passed, but the looked-for deliverance never came, and now all hope is gone.

Matthew Henry's Concise Commentary

8:14-22 At length they begin to see the hand of God lifted up. And when God appears against us, every thing that is against us appears formidable. As salvation only can be found in the Lord, so the present moment should be seized. Is there no medicine proper for a sick and dying kingdom? Is there no skilful, faithful hand to apply the medicine? Yes, God is able to help and to heal them. If sinners die of their wounds, their blood is upon their own heads. The blood of Christ is balm in Gilead, his Spirit is the Physician there, all-sufficient; so that the people may be healed, but will not. Thus men die unpardoned and unchanged, for they will not come to Christ to be saved.
