Or HaChaim on Deuteronomy 11:11/אור החיים על דברים י״א:י״א

1 והארק אשר אתם עוברים שמה, "and the land which you are crossing over to, etc." Why does Moses repeat the words: "the land you are crossing over to," having said something almost identical in verse 10 already? I believe we have to understand these two verses as follows. Although the Torah had already extolled the virtues of the land of Canaan, describing it as a land flowing with milk and honey, the Torah had to contrast it with Egypt which is also a land blessed with excellent produce as the Torah had testified in Genesis 13,10: "like a garden of G'd, like the land of Egypt." Moses explains that whereas Egypt receives its bounty only by means of natural means, without special providence by G'd, it has another disadvantage compared to the land of Canaan in that you have to irrigate the land with back-breaking labour, whereas in the land of Canaan the rain does the irrigating.
