(4) Listen Israel! Hashem is our G-d, Hashem is one. (5) You should love Hashem with all your hearts, all your soul, and all of your money. (6) And these are the mitzvot that Hashem commanded today on your hearts. (7) And you should teach them sharply to your children, in your house, and where you settle, and when you are walking on a path, and when you lay down, and when you stand up. (8) Wear them as a sign on your arm, and they will be a symbol on your forehead; (9) And inscribe them on the doorposts of your households, and on your gates.
I think that this really helps us connect to Shema on a way that we don't usually learn. It is very special that he can connect the number 70 to so many things.
I like the explanation of wholeheartedly. It is simple, yet it still explains the subject well.
I like how Rashi took the word to a different level, and didn't just keep it at a simple explanation.
I don't like that Ramban didn't take a deeper look into the word, but I liked that he quoted Chazal.
I like that Rashi gave an explanation that applies to us every day, since we have to feel like the Torah is new every day.
