The men illustrating the Ha’aretz report (above) were NOT “covering their feet”.
In conversation on Bob’s blog, related to my post below about foot as a possible euphemism for male genitals in the Bible, he points out that there are cases where the phrase “cover his feet” is clearly euphemistic for “going to the bathroom” – to use a more contemporary American euphemism. I entirely agree. It is. Clearly when Saul in 1 Samuel 24:3 goes into the cave to “cover his feet” להסך את־רגליו he is as the Living Bible said going “to the bathroom” (cf. Judges 3:24).
I am left with two problems, do two case make sufficient precedent for seeing euphemisms everywhere, and more importantly, how does this euphemism: “cover … feet” = “go to the bathroom” work? The way it seems to me to make sense is that when one needed to relieve oneself in the fields or on a journey one squatted, thus “covering one’s feet” with ones robe, and hiding the action from passers by. Thus it seems to me the clear euphemism is “cover the feet” = “relieve oneself” and not “foot” = “male organ”.
