C. F. Keil and Franz Delitzsch on Exodus 10:16-17

Exo 10:16-17

This plague, which even Pliny calls Deorum irae pestis, so terrified Pharaoh, that he sent for Moses and Aaron in haste, confessed his sin against Jehovah and them, and entreated them but this once more to procure, through their intercession with Jehovah their God, the forgiveness of his sin and the removal of “this death.” He called the locusts death, as bringing death and destruction, and ruining the country. Mors etiam agrorum est et herbarum atque arborum, as Bochart observes with references to Gen 47:19; Job 14:8; Psa 78:46.
