By what means shall a young man learn

9 By what means shall a young man learn
his way to purify?
If he according to thy word
thereto attentive be.
10 Unfeignedly thee have I sought
with all my soul and heart:
O let me not from the right path
of thy commands depart.

11 Thy word I in my heart have hid,
that I offend not thee.
12 O Lord, thou ever blessèd art,
thy statutes teach thou me.
13 The judgments of thy mouth each one
my lips declarèd have:
14 More joy thy testimonies' way
than riches all me gave.

15 I will thy holy precepts make
my meditätion;
And carefully I'll have respect
unto thy ways each one.
16 Upon thy statutes my delight
shall constantly be set:
And, by thy grace, I never will
thy holy word forget.
