George Haydock's Catholic Commentary
Psalms 118:147
The. Literally, "in maturity." Some think that we should read immaturitate, Greek: aoria, (St. Augustine) "in the dead of the night." The psalmist not only rose at midnight, but before sun-rise to meditate. (Haydock) --- Kimchi says, he only indulged sleep the first three hours. But others believe, that he arose in the third and last watch, ver. 148. (Calmet) --- He got up before the ordinary time, and prayed with earnestness. (Worthington) --- St. Ambrose encourages people to come early to the church, to offer the first-fruits of their hearts, and voice to God; (Calmet) and St. Augustine informs us, that such was the practice of St. Monica. (Confessions ix. 7.) You are not in a higher station than the holy king who said, I rose, &c., ver. 22. (St. Chrysostom, ser. 42. ad pop.) (Berthier)
