Darkness in Scripture (metaphorically taken) signifies ignorance, sin, and misery; and light signifies knowledge, a state of grace, or a state of mirth and jollity; they are both here taken in the latter sense, as light is taken, Esther 8:16 Micah 7:8 Job 18:5 Psalms 97:11; and also darkness is used, Jeremiah 13:16 2 Samuel 22:29 Proverbs 20:20 Joel 2:2 Ezekiel 32:8. The sense is, God hath not brought me into a joyful and prosperous, but into a sad and calamitous, estate and condition.
