Differences in the Ten Commandments
Question
The text of the 10 commandments differs in parshas Yisro and Eschanan.
What are the accepted explanations for the differences. Which text was actually written on the luchos? Is there an opinion that 1 was the text on the 1st luchos and the other on the 2nd luchos?
Another question. I know several people who passed away without children - distant relatives and friends. Is there any inyan for me to light a yarhzeit light for them on their yarhzeit or is it only for the children to do?
Many thanks
