Literary Devices – Shemot 14

• As seen in the Tanakh Lab,¹ the word מצרים appears 26 times in this chapter, more than any other. The repetition highlights the might of Egypt and terror they instill, even as they are about to be defeated. In the panicked words of the Israelites to Moshe in verses 12-13 the word appears a full five times, illustrating the psychological hold that Egypt continues to exert over Israel and the fear that they feel as a result.

• Tanakh Lab – The two related roots of “כבד” and “חזק”, which have appeared many times throughout the exodus narrative in the context of hardening Paroh's heart, appear three times each in Shemot 14 as the story culminates.  Here, though, the root "כבד"  describe how Hashem will be honored through the miracle.  The repetition and wordplay highlight how Paroh’s obduracy led to the crowning miracle of the splitting of the sea.
• Articles – See Prof. Yonatan Grossman's Leitwort who discusses the phenomenon of keywords as a whole,² bringing "כבד" as one example, and R. Nathaniel Helfgot שתי מילים מנחות בסיפור יציאת מצרים, who explores the usages of the two roots כבד and חזק. Both authors note how the repetition of the roots demonstrates Hashem's measure for measure actions during the Exodus.³ 

Amos Hakham⁴ points out a play on words between the Egyptians’ exclamation of “What is this that we have done that we have sent Israel out from serving us?" and the Israelites’ cry of “What is this that you have done to us, to bring us out from Egypt?!” Both express regret at the exodus. Moreover, both exclamations contrast with the question that the Torah states will be asked by Jewish children about the Passover service in the future: “What is this?” (13:14). The despairing “What is this?” of the Egyptians and the Israelites at the time of the exodus will be replaced by the curious “What is this?” of generations of Jews as they commemorate the event.

The following articles contain general discussion of wordplay in Tanakh:

• See Wordplay in Biblical Hebrew: An Eclectic Collection, by Gary A. Rendsburg, for exploration of various forms of Biblical wordplays.
• See Wordplay in Ancient Near Eastern Texts, by Scott B. Noegel, for a book-length treatment of the range of permutations of wordplays in Tanakh and in other Ancient Near Eastern texts⁵

• The words attributed to Paroh in verse 3 are stated as a parallelism:  נְבֻכִ֥ים הֵ֖ם בָּאָ֑רֶץ / סָגַ֥ר עֲלֵיהֶ֖ם הַמִּדְבָּֽר.  In his commentary on the Torah, Robert Alter suggests that this highlights Paroh’s “regal confidence” in his ability to capture the escaped Israelites.
• Verse 9, which describes Mitzrayim’s apparently successful pursuit of the Israelites, is also formulated with parallel structure, also conveying a sense of confidence and majesty, which will shortly be upended:
• וַיִּרְדְּפ֨וּ מִצְרַ֜יִם אַחֲרֵיהֶ֗ם / וַיַּשִּׂ֤יגוּ אוֹתָם֙ חֹנִ֣ים עַל־הַיָּ֔ם
• כׇּל־סוּס֙ רֶ֣כֶב פַּרְעֹ֔ה / וּפָרָשָׁ֖יו וְחֵיל֑וֹ
• עַל־פִּי֙ הַֽחִירֹ֔ת / לִפְנֵ֖י בַּ֥עַל צְפֹֽן

• Fire – Using the concordance demonstrates that fire is often a vehicle of Hashem’s revelation, becoming a symbol thereof as well.  Fire has appeared in the context of the Covenant Between the Pieces, the destruction of Sedom, the plagues, and the pillar of cloud and fire that led the Israelites in the desert.  Fire appears many times subsequently in the Torah, as well, often in the context of divine wrath and destruction.
• Articles – Several articles touch on the symbol:
• See The Eternal Flame, by R. David Silverberg, for an analysis of consuming fire as a symbol of divine punishment and non-destructive fire as a symbol of Hashem’s presence.  
  See קול אלקים מדבר מתוך האש, by R. Amnon Bazak, for analysis of how Torah’s descriptions of the fire of Sinai in Shemot and Devarim are meant to impart three fundamental religious beliefs: God’s incorporeality, the prohibition of idolatry, and the truth of Moshe’s prophecy. 

• Cloud – Using the concordance demonstrates that clouds (like fire) are often a vehicle of Hashem’s revelation, becoming a symbol thereof as well.
• Articles –
• See Pillar of Fire, Pillar of Cloud, by R. Tamir Granot, for analysis of the phenomenon of Hashem’s revelation through natural phenomena such as fire and clouds. He suggests that in Tanakh, the cloud and pillar of fire are not two distinct modes of revelation, but one and the same. God's glory is manifest as fire which is screened by the cloud. It is referred to as one or the other due to the perception of the viewer, who might see fire at night, but only cloud during the day.
• See For the Cloud Rested Upon It, by R. Shimon Klein, for exploration of the distinct symbols of fire and cloud.  He suggests that fire represents Hashem’s actions and manifestation while the cloud represents man’s encounter with Him.
