tn The word in the text is וַיָּסַר (vayyasar), which would be translated “and he turned aside” with the sense perhaps of removing the wheels. The reading in the LXX, Smr, and Syriac suggests a root אָסַר (’asar, “to bind”). The sense here might be “clogged—presumably by their sinking in the wet sand” (S. R. Driver, Exodus, 120).
tn The clause is וַיְנַהֲגֵהוּ בִּכְבֵדֻת (vaynahagehu bikhvedut). The verb means “to drive a chariot”; here in the Piel it means “cause to drive.” The suffix is collective, and so the verbal form can be translated “and caused them to drive.” The idea of the next word is “heaviness” or “hardship”; it recalls the previous uses of related words to describe Pharaoh’s heart. Here it indicates that the driving of the crippled chariots was with difficulty.
tn The cohortative has the hortatory use here, “Let’s flee.” Although the form is singular, the sense of it is plural and so hortatory can be used. The form is singular to agree with the singular subject, “Egypt,” which obviously means the Egyptian army. The word for “flee” is used when someone runs from fear of immanent danger and is a different word than the one used in 14:5.
