Exodus 2:18

And when they came to Reuel their father ,.... Or Ragouel, as the Septuagint; and so Artapanus F19 Ut supra. (Apud Euseb. Praepar. Evangel. l. 9. c. 27. p. 434.) calls him. The Targum of Jonathan has it, their father's father; and so Aben Ezra says he was; and is the sense of others, induced thereto by Numbers 10:29 , but it does not follow from thence: he said:

how is it that you are come so soon today ? it being not only sooner than they were wont to come, but perhaps their business was done in so short a time; that it was marvellous to him that it could be done in it, so quick a dispatch had Moses made, and they through his assistance; and especially it might be more strange, if it was usual, as it seems it was, to be molested by the shepherds.
