Albert Barnes Commentary Psalms 34:19

"Many are the afflictions of the righteous; But Jehovah delivereth him out of them all." — Psalms 34:19 (ASV)

Many are the afflictions of the righteous - This is not intended to affirm that the afflictions of the righteous are more numerous or more severe than the afflictions of other men, but that they are subjected to much suffering, and to many trials. Religion does not exempt them from suffering, but it sustains them in it; it does not deliver them from all trials in this life, but it supports them in their trials, which it teaches them to consider as a preparation for the life to come.

There are, indeed, sorrows which are special to the righteous, or which come upon them in virtue of their religion, as the trials of persecution; but there are sorrows, also, that are special to the wicked - such as are the effects of intemperance, dishonesty, crime. The latter are more numerous by far than the former; so that it is still true that the wicked suffer more than the righteous in this life.

But the Lord delivers him out of them all - See the notes at (Psalms 34:17).
