Exodus 2:11-13

Young's Literal Translation

¹¹ And it cometh to pass, in those days, that Moses is grown, and he goeth out unto his brethren, and looketh on their burdens, and seeth a man, an Egyptian, smiting a man, a Hebrew, [one] of his brethren,

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?'
