Verse 20. — Then Job arose. 80. Discernment profits by temptations. — For to sit belongs to one at rest; to rise up, to one contending. Therefore, to rise upon hearing of adversities is, being made experienced by temptations, to prepare the mind more robustly for the contests. By these temptations discernment also assuredly profits, because it learns to distinguish more subtly the virtues from the vices. Whence also it is well subjoined.
