Awake, why sleepest thou? - This is a solemn and earnest appeal to God to interpose in their behalf, as if he were “asleep,” or were regardless of their sufferings. Compare Psalms 3:7, note; Psalms 7:6, note; Psalms 35:23, note.
Arise, cast us not off for ever - Do not forsake us always. Compare Psalms 44:9. He had seemed to have cast them off; to have forgotten them; to have forsaken them utterly, and the psalmist, in the name of the people, calls on him not entirely to abandon them.
