Exodus 2:15

12 and he turneth hither and thither, and seeth that there is no man, and smiteth the Egyptian, and hideth him in the sand.

13 And he goeth out on the second day, and lo, two men, Hebrews, striving! and he saith to the wrong-doer, `Why dost thou smite thy neighbour?`

14 and he saith, `Who set thee for a head and a judge over us? to slay me art thou saying [it], as thou hast slain the Egyptian?` and Moses feareth, and saith, `Surely the thing hath been known.`

15 And Pharaoh heareth of this thing, and seeketh to slay Moses, and Moses fleeth from the face of Pharaoh, and dwelleth in the land of Midian, and dwelleth by the well.

16 And to a priest of Midian [are] seven daughters, and they come and draw, and fill the troughs, to water the flock of their father,

17 and the shepherds come and drive them away, and Moses ariseth, and saveth them, and watereth their flock.

18 And they come in to Reuel their father, and he saith, `Wherefore have ye hastened to come in to-day?`
