These verses describe the splitting of the Yam Suf before the Jews. This miracle was performed through the medium of the 72-part Divine Name. The Baal HaTurim notes that the word ובקעהו (in verse 16) can be read as בקע והו (Moshe split the sea with the Divine Name of והו ).
The phrase “Ani vaHu” אני והו possesses mystical significance. These three consecutive verses are encrypted the seventy-two three-letter parts of the Divine Name. Each of these three verses contains exactly 72 letters. The three-parts of the Divine name are formed by taking the consecutive letters from each verse, with the first verse read forward, the second verse backward, and the third verse read forward again.

First letter of the first verse is "ו"; last letter of the second verse is "ה" (which is the first letter when read backwards). The first letter of the third verse is "ו". This spells והו. (It is noteworthy that the 49th set of letters is also והו; perhaps this accounts for the two methods to add vowels וָהוּ and וָהוֹ)
The 37th letter of the first verse is "א". The 37th letter of the second verse backwards is "נ". The 37th letter of the third verse is "י". (The 72 letters can be divided into two sets of 36, which establishes the 37th letter the first letter of the second set.)
