Exodus 2:16

13 And he went out the day after and saw two of the Hebrews fighting: and he said to him who was in the wrong, Why are you fighting your brother?

14 And he said, Who made you a ruler and a judge over us? are you going to put me to death as you did the Egyptian? And Moses was in fear, and said, It is clear that the thing has come to light.

15 Now when Pharaoh had news of this, he would have put Moses to death. But Moses went in flight from Pharaoh into the land of Midian: and he took his seat by a water-spring.

16 Now the priest of Midian had seven daughters: and they came to get water for their father's flock.

17 And the keepers of the sheep came up and were driving them away; but Moses got up and came to their help, watering their flock for them.

18 And when they came to Reuel their father, he said, How is it that you have come back so quickly today?

19 And they said, An Egyptian came to our help against the keepers of sheep and got water for us and gave it to the flock.
