Kedoshim: Chapter 13

"I am Hashem your Elohim from the land of Egypt"


Rabbi Elazar wonders why it seems that the title verse is saying there was no Elohim before Yisrael were in Egypt, and Rabbi Shimon explains that Yisrael only knew the glory of God from the time they were in Egypt. From that time they saw many miracles and wonders, and His glory was exposed to them when He parted the sea.
