In contrast, the acrostics in the fifth book are almost perfectly preserved. The acrostics of chapters 111 and 112 are complete, and the acrostic of chapter 119 is complete, with every letter repeated eight times! The lone possible imperfection is chapter 145 which lacks a nun verse. But the fact that all the other acrostics in the fifth book are complete suggests that the nun verse is not missing here, but was omitted intentionally. The nun verse found in the Dead Sea and Septuagint texts of Psalm 145 should be considered a later addition. The nun verse found in these sources is suspicious for other reasons as well.
