For I am... — Literally, because I am fearfully separated or distinguished (see Note on Psalms 26:7; Psalms 40:5), which might mean separated from the womb, i.e., born. (Comp. Galatians 1:15; Psalms 22:10.) Or if the reference is national rather than individual, it would imply, as so frequently, the choice of Israel by Jehovah in distinction to other races.
