Deuteronomy 28:43 Kabbalah: Baal HaSulam's Introduction to Zohar

However, if G-d forbid the opposite occurs, that a Jewish person, considers important the external, the “nations of the world” within him, over the “Israel” within him, as it is written (Deuteronomy 28:34) “ The stranger among you will ascend above you higher and higher, while you will descend lower and lower”. Meaning the external within you, the “nations of the world” within you, will ascend higher and higher, while the internal within you, the “Israel” within you will descend lower and lower. These actions will cause the nations of the world to ascend higher and higher, and overcome the Jewish nation, and lower them to the ground, and the Jewish nation, the internal aspect of the world will descend lower and lower, G-d forbid.
