In "God's Word for Today" David Woods writes:

Psalm 119 is made up of twenty-two strophes (paragraph of poetry), one for each letter of the Hebrew alphabet, and each strophe has eight verses. Each of these verses begins with the Hebrew letter by which their particular strophe is named. Faithlife Study Bible notes that the most prominent feature in translation is the repetition of eight words: law, word (imrath), word (devar), judgments, testimonies, commandments, statutes, and precepts. Psalm 119 is characterized as a Torah Psalm, a wisdom Psalm, and an individual lament. The author is unknown. This Psalm emphasizes the Word of God, using some term for God's Word in almost every verse. Preacher's Commentary notes that the psalmist was involved in a real battle with enemies, but also was struggling with himself to do what was right and good. New Bible Commentary calls this Psalm the Golden ABC of God's Word.
Discussion: Early American education was profoundly impacted by The New England Primer, Webster's Speller, and the McGuffey Readers. How might our lives be impacted if we used Psalm 119 as a spiritual “primer”?
