Arise, cry out in the night,.... That is, O daughter of Zion, or congregation of Israel, as the Targum; who are addressed and called upon by the prophet to arise from their beds, and shake off their sleep, and sloth, and stupidity, and cry to God in the night season; and be earnest and importunate with him for help and assistance.
Aben Ezra rightly observes, that the word used signifies a lifting up of the voice both in singing and in lamentation; here it is used in the latter sense; and denotes great vehemency and earnestness in crying unto God, arising from deep distress and sorrow, which prevents sleep:in the beginning of the watches; either at the first of them; so Broughton renders it, "at the first watch"; which began at the time of going to bed: or at the beginning of each of them; for with the ancient Jews there were three of them; in later times four: or in the beginning of the morning watch, as the Targum; very early in the morning, before sun rising; as they are called upon to pray late at night, so betimes in the mottling:pour out thine heart like water before the face of the Lord; use the utmost freedom with him; tell him, in the fullest manner, thy whole case, fit thy complaints; unbosom thyself to him; keep nothing from him; speak out freely all lily soul needs; do all this publicly, and in the most affectionate way and manner, thy soul melted in floods of tears, under a sense of sin, and pressing evils for it.
