_Lucerna pedibus meis_.
Thy word is a lantern unto my feet: and a light unto my paths.
106 I have sworn, and am stedfastly purposed: to keep thy righteous
judgements.
107 I am troubled above measure: quicken me, O Lord, according to
thy word.
108 Let the free-will offerings of my mouth please thee, O Lord:
and teach me thy judgements.
