Kabbalah su Numeri 14:8

And as the Zohar in Shlach Lecha says regarding the advice of the Evil Inclination: 66. What did these faithful say? “If Hashem delights in us...and give it us” (Bemidbar 14:8), MEANING THAT if a person strives with a willing heart for the Holy One, blessed be He, HE WILL MERIT HER, since He only wants his heart. And they will preserve that Holy Sign, THAT IS THE HOLY COVENANT, as is written: “Your people also shall be righteous: they shall inherit the land forever” (Yeshayah 60:21), MEANING THOSE WHO PRESERVE THE COVENANT, WHO ARE CALLED RIGHTEOUS.
