Psalms 37:26

He is ever merciful, and lendeth; and his seed is blessed.

The upright are characterized by continual mercy and a generous willingness to lend to others. This merciful and giving spirit is not occasional but ever-present in their lives. As a result of such righteousness, blessing rests upon their children after them. Shem's respectful and honoring treatment of his father exemplified this upright conduct, and the godly line that descended from him shows the promised blessing resting upon his seed.
