Psalms 18:28

“To give one light is to make prosperous (Job 18:5-6; Job 21:17). thou--is emphatic, as if to say, I can fully confide in Thee for help.”

“For thou wilt light my candle - Margin, lamp. The word lamp best expresses the idea. In the Scriptures light is an image of prosperity, success, happiness, holiness, as darkness is the image of the opposite. See the notes at Job 29:2-3; compare also Job 18:6; Job 21:17; Proverbs 20:27; Proverbs 24:20; Psalms 119:105; Psalms 132:17; Isaiah 62:1.
