Psalms 119: 165, 168, 171 - 172, 174 - 175
165 Great peace have those who love thy law; nothing can make them stumble.
168 I keep thy precepts and testimonies, for all my ways are before thee.
171 My lips will pour forth praise that thou dost teach me thy statutes.
172 My tongue will sing of thy word, for all thy commandments are right.
174 I long for thy salvation, O LORD, and thy law is my delight.
175 Let me live, that I may praise thee, and let thy ordinances help me.
