George Haydock's Catholic Commentary
Psalms 77:34
Morning. Those who were spared pretended to repent. (Haydock) --- Afflictions are the source of much good. But the Israelites are blamed for their inconstancy and deceit. (Calmet) --- They came with apparent earnestness (Haydock) to offer the morning sacrifice (Worthington) under affliction. (Menochius)
