Eruvin 18: If She Walks in Front of You, You May Not Follow

A small portion of a long mishnah: the case of arranging boards as an enclosure around a well, where 4 boards look like 8, or 8 that look like 12. The key being the "dyumadim" - double-boards. Then the daf moves on to aggadot connected to that "dyu" (two). Specifically, Adam and Eve, who were also two, but one. Also an observation on Eve as a receptacle for a baby. And the image of God as Adam's "best man," accompanying him at his wedding, putting God into the equation for both of them. Plus: A man should not walk behind a woman, for reasons of modesty... Which several biblical men seem to defy. Manoach (father of Samson) is singled out as an ignoramus. And finally, a hierarchy of following behind a lion, a woman, and idolatry.
