I mourn. — A verb found in this form only in three other passages, always with the idea of restlessness — e.g., Genesis 27:40, of the roving life of a Bedouin; Jeremiah 2:31, of moral restlessness; Hosea 12:1, of political instability. Here it may either indicate that bodily restlessness which often serves as an outlet of grief:
“Hard mechanic exercise,
Like dull narcotics, numbing pain,”
or the distracted state of the mind itself.
And make a noise. — Better, and must roar, the form of the verb expressing the compulsion which the sufferer feels to give vent to his feelings in groans and murmurs. (See Note on Psalms 42:5.)
