The Church recites this psalm for the sick. Those who assist them may hope for similar treatment. But such as are not scandalized at Christ, on account of his poverty and afflictions, may be pronounced blessed, (Luke vii. 23.) as He will deliver them from distress, if they place their confidence in Him. (Worthington)

Preserve. Hebrew, “will preserve....and thou wilt not deliver him unto the will of his enemies.” (Protestants)

But St. Jerome has, “and he will not,” &c. (Haydock)

Sixtus V reads, “into the hands of his enemy,” after St. Augustine, &c. Others add, “he will purify his soul from, or on the earth.” (Calmet)

Our Lord will give to such servants more grace in this life, and glory in the next, nor will he suffer them to yield to temptation. (Worthington)

He will defend them and heal them, when sick. (Calmet)
