This is my comfort - While enduring our harsh captivity, we anticipated our enlargement; and thy word of promise was the means of keeping our souls alive.
This is my comfort in my affliction - Compare Romans 15:4. The word here rendered “comfort” occurs only here and in Job 6:10. The obvious meaning is, that his only consolation in his affliction was derived from the word of God; the word which had caused him to hope, and the word by which he had been quickened or made alive. The particular design of this is to show the value of the word of God as a source of comfort in trouble.
For thy word hath quickened me - Has made me alive; or, caused me to live. That is, the word, the truth of God, had been the instrument of calling him from the death of sin, and of imparting to him new life, or had been the means of his regeneration. Compare James 1:18; 1 Corinthians 4:15; Hebrews 4:12; 1 Peter 1:23. As it was by this “word” that he had been made alive, so his only comfort was in that word, and it was to him a just ground of consolation that God had brought him from the death of sin, and had imparted to him spiritual life.
