Commentary for Ecclesiastes 4:11
גַּ֛ם אִם־יִשְׁכְּב֥וּ שְׁנַ֖יִם וְחַ֣ם לָהֶ֑ם וּלְאֶחָ֖ד אֵ֥יךְ יֵחָֽם׃
Again, if two lie together, then they have warmth; but how can one be warm alone?
Rashi on Ecclesiastes
They can be warm. [To be understood] according to its apparent meaning, regarding male and female, who are aroused by one another and procreate.16Alternatively, these verses refers to the performance of a mitzvah, i.e., if each one performs a mitzvah on his own then if he slackens off, there is no one to encourage him and “uplift him.” However, when two people perform a mitzvah together, it adds “warmth” to their performance of the mitzvah. (Divrei Avrohom)
