For now thou numberest my steps; rather, but now. Job, at this point, proceeds to contrast his actual condition with the ideal one which (in verses 13-15) his imagination has conjured up. God's actual attitude towards him he regards as one, not of protecting love, but of jealous hostility.
His "steps" are observed, counted—every divergence from the right path is noted—a false step, if he makes one, is at once punished. Dost thou not watch over my sin? (comp. Job 10:14). Job's sins, he thinks, are watched for, spied out, taken note of, and remembered against him.
