They keep trying to frighten you, lying in wait and digging up whatever they can against you.
When your enemies keep trying to frighten you, lying in wait and searching out everything against you, however many they are, don't give in. In the Greek Psalter Athanasius sang, their blows are no more than children's arrows. Sing Psalms 64, 65, 70 and 71.
Letter to Marcellinus
For the same situation he also named Psalm 65, Psalm 70 and Psalm 71.
