"[88] The school of Rabbi Ishmael reasoned from the meaning of the word "in the midst" (בְּתוֹךְ‎, be-tokh) in Exodus 14:22 to resolve an apparent contradiction between two Biblical verses.

Pharaoh concluded that the Egyptians should afflict the Israelites with water, because as indicated by Isaiah 54:9, God had sworn not to bring another flood to punish the world.

[107] The Gemara counted Exodus 15:18, "The Lord shall reign for ever and ever," among only three verses in the Torah that indisputably refer to God's Kingship, and thus are suitable for recitation on Rosh Hashanah.

A Baraita taught at the school of Rabbi Eliezer ben Jacob said that wherever Scripture employs the expression נֶצַח‎, nezach; סֶלָה‎, selah; or וָעֶד‎, va'ed; the process to which it refers never ceases.

"[136] Reading the account of Massah and Meribah in Exodus 17:1–7, Isaac Abravanel argued that if the Israelites lacked drinking water, then they were justified in complaining, and to whom should they have turned if not to their leader Moses?

[137] The parashah is discussed in these modern sources: Moshe Greenberg wrote that one may see the entire Exodus story as "the movement of the fiery manifestation of the divine presence.

That the song of Exodus 15:1–19 does not contain even one definite article indicated to Kugel (along with other ancient morphological and lexical features) that "it has been preserved from a very early stage of the Hebrew language and thus may be one of the oldest parts of the Bible.

Oden grouped Exodus 15 along with Judges 5, Habakkuk 3, and Psalm 68 as exemplars of holy war hymns that revealed the religion of the Tribal League that preceded the formation of Israel.
