They gather themselves together; after they have severally employed their thoughts against me, they meet together to compare their thoughts, and to put them in execution. They hide themselves; they lurk secretly, either that they may pry into all my most private actions, or that they may surprise me with mischief unawares. Compare Psalms 10:8 Proverbs 1:11. They mark my steps, i.e. all my goings and doings, that they may find some occasion to reproach or entangle, and so destroy me. My soul, or life, to wit, to take it away from me.
