12 Gesenius notes that the sign of the accusative, often omitted in poetry, is not found in this entire song ( §117.b).
13 The word is a substantive, “choice, selection”; it is here used in the construct state to convey an attribute before a partitive genitive—“the choice of his officers” means his “choice officers” (see §128.r).
14 The form is a Qal passive rather than a Pual, for there is not Piel form or meaning.
15 The verb form is יְכַסְיֻמוּ (yékhasyumu) is the Piel preterite. Normally a vav (ו) consecutive is used with the preterite, but in some ancient poems the form without the vav appears, as is the case frequently in this poem. That such an archaic form is used should come as no surprise, because the word also uses the yod (י) of the root ( §75.dd), and the archaic suffix form ( §91.l). These all indicate the antiquity of the poem.
16 The parasynonyms here are תְּהֹמֹת (téhomot, “deep, ocean depths, deep waters”) and מְצוֹלֹת (métsolot, “the depths”); S. R. Driver says properly the “gurgling places” (Exodus, ).
