Augustine of Hippo
It could be interpreted that it needed to convey, ‘Listen to me, for I call out to You.’ However, the statement becomes, ‘To You I call, for You will listen to me’; and then, seemingly in response to the inquiry regarding how he demonstrates his cry for help, he highlights the result of his plea to God—namely, that God has indeed responded to him. It is as though he asserts: I demonstrate here that I have called out, because You have heard my voice.
I earnestly and devotedly lifted my prayers to you, seeking the strength I desired, and you listened even when my pleas were less fervent. Please, incline your ear to me and attend to my words. Do not let your attentiveness abandon my humbled state.
