The heart is the "home of the personal life," and hence a man is designated, according to his heart, wise (1Ki 3:12, etc.), pure (Psa 24:4; Mat 5:8, etc.), upright and righteous (Gen 20:5,6; Psa 11:2; 78:72), pious and good (Luk 8:15), etc. In these and such passages the word "soul" could not be substituted for "heart."
