But thou hast not called upon me. The Jews had never been greatly given to prayer. They were a "practical" people, active, energetic, hard-working, busily employed in handicrafts, commerce, or agriculture.
David and Daniel, who prayed three times a day (Psalms 55:17; Daniel 6:10), were probably exceptions to the general rule. At any rate, it appears here that in the exile the nation had neglected prayer.
No doubt there was a nucleus of "faithful men," who did as Daniel did. But with the mass it was otherwise. Hard toil occupied their time. Despair made dull their hearts. They looked for no alleviation of their lot, and lived on in a sort of apathy.
But thou hast been weary of me; rather, for thou hast wearied of me. Thou hast left off praying, because thou wast weary of my service.
