Psalm 119 and Psalm 136, both in Book Five, are presented as showing God's law as a practical, daily guide for the pilgrimage out of spiritual Egypt toward His Kingdom. Psalm 119 praises the law as a way of life rather than legal minutiae or stern warnings, and it is called a New Testament psalm because it focuses on the heart. The law cleanses, brings joy, counsels, gives hope, peace, and liberty, and makes sense of affliction (verses 9, 11, 71, 165). Its eight or more synonyms for God's instruction, such as derek, torah, edah, piqqudim, chuqqim, and dabar, add depth and variety. Almost every verse is a prayer addressed to God, and beneath the praise runs a veiled story, possibly of Jeremiah, with four characters: God, the psalmist, a faithful remnant, and wicked enemies, including princes and kings, who have imprisoned him unjustly. Going stanza by stanza, he moves from weakness, loneliness, and persecution to trust, repentance, and growth in character, ending with a plea to be sought like a lost sheep. The story's rescue is not recorded, but Jeremiah's later release is cited. The psalm stands for the faithful Christian enduring trials, relying on God's Word. The study closes with Psalm 136, recalling God's mercy in bringing Israel out of Egypt with a strong hand and through the wilderness.

The psalmist in Psalm 119 expresses profound admiration for God's law, dedicating 176 verses to its praise. He views the law not as a burden, but as a source of guidance throughout life, whether in times of thriving or suffering. His love for the law stems from its ability to provide direction in every situation, offering wisdom and understanding to navigate life's challenges. In verses 97-106, the psalmist declares his deep affection for God's law, meditating on it constantly. He credits the law with making him wiser than his enemies, granting him understanding beyond his teachers and the ancients, and helping him restrain his feet from evil paths. The law is a lamp to his feet and a light to his path, illuminating his understanding and guiding his conduct. He finds God's words sweeter than honey, and through them, he gains insight to hate every false way, swearing to keep God's righteous judgments. The psalmist uses various terms to describe God's law throughout Psalm 119, reflecting its multifaceted nature. In the first stanza, verses 1-8, he speaks of the blessedness of those who walk in the law of the Lord, keep His testimonies, follow His ways, observe His precepts, adhere to His statutes, learn His commandments, and uphold His righteous judgments. Additional terms like "word," "truth," and "saying" appear in subsequent verses, emphasizing the breadth of God's revelation. These terms collectively underscore that the law encompasses all of God's instruction, not limited to a single aspect but covering the entirety of His guidance for living. The emphasis in Psalm 119 is on living by God's Word as a practical way of life. From the very first verse, the blessedness is for those who walk according to the law of God and keep His statutes. It is not merely about knowing the law academically, but experiencing and applying it in the many situations of life. The law is portrayed as a priceless tool that God has provided, essential for growth in character and for walking the path He has illuminated.

Book Five of the Psalms is covered by looking at the Hallel (the seven Psalms before Psalm 119), the Songs of Ascents (the Psalms after it), and Psalm 119 itself. Psalm 119 is a long meditation on God's law and way of life, and it fits between the Hallel's praise for redemption and the spiritual life lessons of the Ascents, which move from trial, to faith, to praise. It is the longest psalm and longest chapter in the Bible, with 176 verses, and it sits just after Psalm 117, the shortest chapter, and Psalm 118, which marks the Bible's center. It is a perfect expanded acrostic: eight verses for each of the 22 Hebrew letters, each stanza with its own theme, and nearly every verse referring to God's Word. This hammering on one theme in many forms reflects the Hebrew use of repetition and parallelism, which Deuteronomy 6:7 grounds in God's way of teaching by repeated "sharpening." Psalm 119 has no superscription. Tradition credits David, partly because of Psalm 19:7-11, which serves as its kernel. Internal clues point to a persecuted man who speaks before kings and weeps over his people. These clues also fit Jeremiah, who may have written the acrostic chapters of Lamentations and who rejoiced in God's Word and the law written on the heart. The author remains uncertain. The psalm presents God's law as the perfect revelation of His mind and character, profitable for equipping the man of God.
