77 Heb “And he said.”
78 The conjunction vav (ו) joins Reuel’s question to what the daughters said as logically following with the idea, “If he has done all that you say, why is he not here for me to meet?” (see §154.b).
79 This uses the demonstrative pronoun as an enclitic, for emphasis (R. J. Williams, Hebrew Syntax, 24, §118). The question reads more literally, “Why [is] this [that] you left him?”
80 The imperfect tense coming after the imperative indicates purpose.
81 Heb “bread,” i.e., “food.”
