The prophet in this verse personates the church, and brings her in bespeaking the enemy in this manner:
Rejoice not; let it be no pleasure or matter of glorying to time, that the day of calamity hath overtaken me.
Against me; Israel of God, the remnant, the faithful, which are the church of God.
O mine enemy; O Assyria, Edom, or Babylon. When I fall, into a low condition, into deepest distresses, I shall arise; I shall not always lie in them, God will raise me out of them.
When I (the prophet intends the good, the few righteous ones among those degenerate multitudes) sit in darkness, when affliction, war, famine, and captivity, as a dismal cloud, shall cover us, and benight the daughter of light, when fallen as low as a captive,
the Lord shall be a light unto me; shall support, comfort, and deliver me, his presence and favour shall, as the sun rising, dispel the darkness of the night. This is spoken more especially concerning Judah.
