The answer depends on the manuscript and tradition we read: Psalms are segmented differently from as early as the Dead Sea Scrolls and the Septuagint and continuing through the medieval Hebrew manuscripts of the Masoretic Text.
What did the sea see to make it flee? Who caused the mountains to skip like rams?
Psalm 116:15 declares the death of the righteous to be yaqar, often translated as “precious,” to God. To avoid this message some scholars reinterpret the word yaqar to mean “difficult” or “grievous,” but a better solution is available.
Short does not mean simple: Psalm 117 is one of the more difficult psalms. It is only two verses long and exhorts non-Israelites to praise YHWH. Why would such a psalm be written? A look at the worldview of the exilic prophet Deutero-Isaiah provides one answer, while reading this psalm together with the beginning of Psalm 118 provides another.
Psalm 114, a late psalm, is exceptional in its structure and content. These tightly structured eight verses, which reflect several non-Torah traditions, use Egypt symbolically, to encourage the exiles to return from Babylonia.
The liturgical compilation Hallel (“praise”) opens with Psalm 113. Originally, this psalm was recited by women who gave birth after being barren, reminiscent of the song of Channah in 1 Samuel 2. A close look, however, suggests that its opening verses are a later supplement meant to introduce the larger Hallel collection.
