Psalms 119: 89 - 91, 130, 135, 175
89 For ever, O LORD, thy word is firmly fixed in the heavens.
90 Thy faithfulness endures to all generations; thou hast established the earth, and it stands fast.
91 By thy appointment they stand this day; for all things are thy servants.
130 The unfolding of thy words gives light; it imparts understanding to the simple.
135 Make thy face shine upon thy servant, and teach me thy statutes.
175 Let me live, that I may praise thee, and let thy ordinances help me.
