171. The desire to attain to like virtues also stands one in good stead; Cic de Off. I. 17, § 55. just as again good-will brings about a likeness in character. For Jonathan the king’s son imitated the gentleness of holy David, because he loved him. Wherefore those words: “With the holy thou shalt be holy,” Ps. xviii. 26. seem not only to be concerned with our ordinary intercourse, but also to have some connection with good-will. The sons of Noah indeed dwelt together, and yet their characters were not at all alike. Esau and Jacob also dwelt together in their father’s house, but were very unlike. There was, however, no good-will between them to make the one prefer the other to himself, but rather a rivalry as to which should first get the blessing. Since one was so hard, and the other gentle, good-will could not exist as between such different characters and conflicting desires. Add to this the fact that holy Jacob could not prefer the unworthy in son of his father’s house to virtue.
