Exodus 2:12 KJV

10And the child grew, and she brought him unto Pharaoh’s daughter, and he became her son. And she called his name Moses: and she said, Because I drew him out of the water.

11And it came to pass in those days, when Moses was grown, that he went out unto his brethren, and looked on their burdens: and he spied an Egyptian smiting an Hebrew, one of his brethren.

12And he looked this way and that way, and when he saw that there was no man, he slew the Egyptian, and hid him in the sand.

13And when he went out the second day, behold, two men of the Hebrews strove together: and he said to him that did the wrong, Wherefore smitest thou thy fellow?

14And he said, Who made thee a prince and a judge over us? intendest thou to kill me, as thou killedst the Egyptian? And Moses feared, and said, Surely this thing is known.
