George Haydock's Catholic Commentary
Job 40:27
Speak. Hebrew, "do." (Haydock) --- Thy rash attempt will prove thy ruin. If thou escape, thou wilt not dare to engage again. (Calmet) --- Septuagint, "Wilt thou lay thy hand upon it, remembering the battle with its body? and let it not be done any more. (28.) Hast thou not seen it, nor been astonished at what has been said?" (Haydock)
