George Haydock's Catholic Commentary
Psalms 108:14
Out. As children derive great advantages from the piety of their parents, so they also feel the punishment of their crimes, when they imitate them, Deuteronomy xxiv. 16., and Ezechiel xviii. 20. If they share in the afflictions of their family, and are free from sin, this must be considered as a trial, and they will be amply rewarded in a future world. God is the arbiter of the life and death of all. External miseries may afflict both the just and sinners; but the motive for their being sent is very different. The Jews prayed, Let his blood be upon us, and upon our children; (Matthew xxvii. 25.) and they became chargeable with all the crimes of their ancestors, Matthew xxiii. 35. (Calmet)
