Exodus 2:12-14 King James Version (KJV)
12 And 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.
13 And 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?
14 And 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.
