Subtilty; or rather, prudence, as this word is used, Proverbs 3:21, Proverbs 5:2 8:5,12, which elsewhere is taken in an evil sense for craft or subtilty. The simple; such as want wisdom, and are easily deceived by others, and therefore most need this blessing. The young man, which wants both experience and self-government.
