While deploring my unfinished state, my hope is that you will bring your merciful dealings in me to perfection, until I attain that utter peace which all that is within me and all my outward being will enjoy with you, when death shall be swallowed up in victory.
—Augustine, The Confessions
Psalm 119 closes with the voice of entreaty. The psalmist asks God to accept his prayer. There is something uncertain and yet hopeful in his voice. His tone is one of optimism seasoned with humility. This is not a contradiction. It is an achievement. With this same hope, speak this last stanza.
169 May my cry come before you, O LORD; give me understanding according to your word.
170 May my supplication come before you; deliver me according to your promise.
171 May my lips overflow with praise, for you teach me your decrees.
172 May my tongue sing of your word, for all your commands are righteous.
173 May your hand be ready to help me, for I have chosen your precepts.
174 I long for your salvation, O LORD, and your law is my delight.
175 Let me live that I may praise you, and may your laws sustain me.
176 I have strayed like a lost sheep. Seek your servant, for I have not forgotten your commands.
Psalm 119 has no real closure. It just ends. I have strayed like a lost sheep. Seek your servant, for I have not forgotten your commands. These last eight verses could easily be substituted anywhere in the psalm and with little interruption to the flow.
Psalm 119 ends soberly.
And there is justice in such an end. I am not sure it should end any other way.
