Adam Clarke's Bible Commentary Verse 3. For, lo, they lie in wait for my soul ] For my life. See the passages referred to above.
Matthew Henry Commentary
Verses 1-7 - In these words we hear the voice of David when a prisoner in his ow house; the voice of Christ when surrounded by his merciless enemies the voice of the church when under bondage in the world; and the voic of the Christian when under temptation, affliction, and persecution And thus earnestly should we pray daily, to be defended and delivere from our spiritual enemies, the temptations of Satan, and the corruptions of our own hearts. We should fear suffering as evil-doers but not be ashamed of the hatred of workers of iniquity. It is no strange, if those regard not what they themselves say, who have mad themselves believe that God regards not what they say. And where ther is no fear of God, there is nothing to secure proper regard to man.
