Here 106:48 is more than the end of this psalm. It is the closing statement for all of Book 4 of the Psalms, which starts at Psalm 90 and ends with Psalm 106.
This refers to two extremes and means for all time. See how you translated this in [Psalms 41:13](../041/013.md). AT: "for all eternity" (See: [[rc://en/ta/man/translate/figs-merism]])
