[12:34]  ¹ tn The imperfect tense after the adverb טֶרֶם (terem) is to be treated as a preterite: “before it was leavened,” or “before the yeast was added.” See GKC 314-15 §107.c.

[12:35]  ² tn The verbs “had done” and then “had asked” were accomplished prior to the present narrative (S. R. Driver, Exodus, 99). The verse begins with disjunctive word order to introduce the reminder of earlier background information.

[12:35]  ³ tn Heb “from Egypt.” Here the Hebrew text uses the name of the country to represent the inhabitants (a figure known as metonymy).

[19:10]  ⁴ tn This verb is a Piel perfect with vav (ו) consecutive; it continues the force of the imperative preceding it. This sanctification would be accomplished by abstaining from things that would make them defiled or unclean, and then by ritual washings and ablutions.

[19:10]  ⁵ tn The form is a perfect 3cpl with a vav (ו) consecutive. It is instructional as well, but now in the third person it is like a jussive, “let them wash, make them wash.”
