George Haydock's Catholic Commentary
Psalms 138:19
If. Hebrew, "surely." (Houbigant) --- From me. How long shall I be forced to live among the enemies of the Lord? (Calmet) --- Since he will reward the good, and punish the wicked eternally, I renounce the society of the latter. (Worthington) --- He specifies murderers, as he had described the wonderful formation of man. (Menochius)
