119:9 thy word. The second stanza begins with an earnest desire for cleansing, a cleansing that can only be applied through God’s Word (Ephesians 5:26). Appropriately the answer comes through the Hebrew word dabar, translated simply as “word;” dabar is by far the most frequently used word for “Word” in the Scriptures, especially for “the Word of the LORD.” Note its first use in Genesis 15:1.
119:10 not wander. With far less self-confidence than before his cleansing through the Word, the young man realizes his deep dependence on the Lord, on prayer, and on the Word, calling out for strength not to “wander” away from God’s written will.
119:11 hid in mine heart. How vitally important it is to memorize Scripture, hiding God’s Word in both heart and mind, if we are to have daily victory over sin in our lives. Here the “young man” uses the eighth and final word for the Scriptures in this psalm, Hebrew imrah, again translated simply by “word,” thus emphasizing not just a concept or thought but the very words of God.
