9. Rejoice, O bochur, in thy yaldut (youth); and let thy lev cheer thee in the yamim of thy bechurim (youth), and walk in the ways of thine lev, and in the sight of thine eynayim; but have da'as of this; that for all these things HaElohim will bring thee into mishpat.
10. Therefore banish ka'as (sorrow) from thy lev, and put away ra'ah from thy basar; for yaldut and shacharut (prime of life) are hevel.
