Exodus 2:10-12

Young's Literal Translation

¹⁰ And the lad groweth, and she bringeth him in to the daughter of Pharaoh, and he is to her for a son, and she calleth his name Moses, and saith, `Because -- from the water I have drawn him.'

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.
