Exodus 2:16-17; Exodus 2:19; Exodus 32:20
Now the priest of Midian had seven daughters: and they came and drew water, and filled the troughs to water their father's flock.
And the shepherds came and drove them away : but Moses stood up and helped them, and watered their flock.
And they said , An Egyptian delivered us out of the hand of the shepherds , and also drew water enough for us, and watered the flock.
And he took the calf which they had made , and burnt it in the fire, and ground it to powder , and strawed it upon the water, and made the children of Israel drink of it.
