“All the children of Israel had light in their dwellings.”
– Exodus 10:23, JPS 1917 Tanach
Three days of darkness fell upon Egypt, as the ninth plague was enacted. Yet, there was light in the dwellings of the Children of Israel, who lived apart from the Egyptians in the land of Goshen. This is in accord with the declaration made several times, in regard to the plagues, that the L-RD would differentiate between the Egyptians and Israel. Perhaps, this is the most striking example, whereof somehow B’nei Yisrael had light in Goshen, whereas the rest of Egypt experienced utter darkness for three days. How can this be explained?
The Targum infers that the light served the purpose of enabling the righteous to be occupied with good deeds within their dwellings (Targum Yonatan, Exodus 10:23, sefaria.org). Or HaChayim alludes to the origin of this light as having to do with the righteousness of the Children of Israel. By this allusion, in all likelihood, he was referring to the idea of the pintele yid – the inner spark.
Despite a person’s best efforts, we often fail to even live up to our own standards of righteousness, let alone G-d’s standard; yet, there is flame within that may always call us to return to Him. This is the pintele yid, the inner essence, wherein the flickering flame of divinity, yearns to be kindled by acts of righteousness (mitzvoth).
“For the commandment is a lamp, and the teaching is light.”
