출애굽기 16:29의 주석

ראו SEE with your very eyes (i. e. the word is used literally and not figuratively in the sense of “consider”) that the Lord in His glory (i. e. the Lord Himself) admonishes you regarding the Sabbath, for, behold, a miracle is performed for you on the eve of every Sabbath in that He gives you then bread for two days.

ראו!, “try and understand!”

ראו כי ה׳ נתן לכם השבת, "See that the Lord has given you the Sabbath, etc." I have already explained that Moses felt that he did not have to spell out this commandment for the people as they had witnessed what happened and surely could draw the right conclusions therefrom. Seeing that G'd personally had revealed this commandment to them, he felt that they had absorbed it with the most potent of their senses, the sense of sight. When he said to the people: "let no one leave his place (of abode), he merely explained that the reason that G'd had not made any manna fall on that day was to save the people the bother to go and pick it up.
