Likutei Moharan 47:7/ליקוטי מוהר"ן מ״ז:ז׳

17. And behold, the entire world is sustained on an influx of bounty from the Land of Israel, as is known. And the Land of Israel itself receives the bounty from truth, the attribute of Yaakov, as is said, “Give truth to Yaakov.”

2[Yaakov] is also an aspect of Tiferet, which is an encompassing of the colors. He also corresponds to ShaMaYiM (heavens): aiSh (fire) and MaYiM (water), which is also an encompassing of the colors.

3This is also hinted at in the Torah: “a land that eats its inhabitants.” For it is difficult [to understand]. Yes, it is true that the spies said something false. But how could their lie be written in the Torah, which is truth? It must therefore be that in these words there is an allusion to something true.

4There is a hint here to what is mentioned above: “a land that eats.” That is to say, its eating and bounty are from the aspects of “its inhabitants.” This is an aspect of “Yaakov lived,” for, as explained, he is the Attribute of Truth.

5[Yaakov] is also an aspect of tefilin, which is called pe’er, the attribute of Yaakov.
