Thou [art] good, and doest good; teach me thy statutes.
Ver. 68. Thou art good, and doest good] Good in thyself (indeed there is none good but thyself) and good to thy creatures, inexpressibly bounteous and beneficial.
Teach me thy statutes] And so impart unto me thy special goodness, that I may resemble thee in being and doing good; full of goodness, filled with knowledge, Romans 15:14 .
