Exodus 2:12

He looked this way and that way. — To see that no one observed him.

He slew the Egyptian. — Jewish commentators gloss over the act, or even eulogise it as patriotic and heroical. But it was clearly the deed of a hasty and undisciplined spirit. The offence did not deserve death, and if it had, Moses had neither legal office nor Divine call, justifying him in making himself an executioner. The result was, that, by his one wrong act, Moses put it out of his power to do anything towards alleviating the sufferings of his brethren for forty years.

Hid him in the sand. — To the east of the Delta the sand creeps up close to the cultivated grounds. There are even patches of it within the Delta itself. Moses naturally remembered that he dug the grave “in the sand.” Any other writer would probably have said “in the ground.”
