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.
