Themes from the Egyptian Great Hymn of the Aten, the divine sun disk, appear in Psalm 104: dangerous animals at night, human activity during the day, a focus on humans as opposed to Israelites, the great power of water, and many more.

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.

The Torah prescribes the observance of festivals on very specific dates, but does not explain how the calendar must be reckoned: Is it lunar? Is it solar? Does it follow some other scheme? And why is the Torah silent on this?
