John Trapp on Ezekiel 29:9

Ver. 9. Becauſe he hath ſaid, The river is mine, and I have made it] With this proud ſpeech he is twice twitted, ſee ver. 3. The Egytians ſo truſted in their river Nilus, as if they needed no help from heaven. Aegyptus ſine nube ferax, ſaith Claudian. Epigram. 6. And Lucan to like purpoſe: Terra ſuis contenta bonis, non indiga mercis Aut Jovis: in ſolo tanta eſt fiducia Nilo. How much better might God have ſaid to theſe Egyptians, then Veſpaſian did, Haurite à me tanquam à Nilo, Come ye to Me the fountain of living waters, and hew not out thus to your ſelves broken ciſterns that can hold no water! But they uſed in mockery to tell the Grecians, that if God ſhould forget to rain, they might chance to ſtarve for it: they thought the rain was of God, but not the river: Te propter nullos tellus tua poſt ulat imbres: T[illegible: 1 letter]bul. de Nilo. Arida nec pluvio ſupplicat herba Jovi. God therefore threateneth hers to dry it up, and ſo he did: Ingratitude forfeiteth all. In the reign of Cleopatra, Nilus overflowed not the banks for two years together, ſaith Seneca: he brings in Callimachus telling of a time, wherein it had not done ſo for nine years ſpace. Hence Ovid, Creditur Aegyptus caruiſſe juvantibus arva Imbribus, atque annis ſicca fuiſſe novem, Art. lib. 1. [non-Latin text not transcribed]. Athenaeus. [non-Latin text not transcribed]. Nazianz.. Thus their gold-flowing and fruit-giving river failed them, becauſe they attributed too much to it. In Joſeph's time they had ſeven years famine.
