"Vayovo'u ho'anoshim al hanoshim, kol n'div leiv - And the men came with the women, all those whose hearts wished to donate"
Rashi says: "im hanoshim, usmichim lahem - (they came) with the women, and close to them".
I've been wondering for many years about this posuk, what about tznius issues? Was there no mechitzah?
Boruch Hashem, today I was zoche to a p'shat! The Yetzer Horah can only find his place in a person who is a mekabel, a 'taker'. Someone who is a nosein, a 'giver', won't do any aveiros. The essence of an aveiro is [usually] trying to have the benefits of this world without its corresponding responsibilities. Taking from Hashem without giving Him anything. Someone who is COMPLETELY a 'giver' commits no aveiros. This point is discussed extensively on this holy site.
The pasuk is telling us that those who were COMPLETE 'givers' were able to come together with the women without any problems. Vayovo'u ho'anoshim al hanoshim, but only kol n'div leiv.
We live in a world where we can't possibly cut ourselves off from women completely. The only way for us to really be able to handle the challenges properly, is by changing our life's motivations from being "takers" to "givers" - one step at a time.
