'Pit' in the Bible
Now then, come and let us kill him and throw him into one of the pits (cisterns, underground water storage); then we will say [to our father], ‘A wild animal killed and devoured him’; and we shall see what will become of his dreams!”
Reuben said to them, “Do not shed his blood, but [instead] throw him [alive] into the pit that is here in the wilderness, and do not lay a hand on him [to kill him]”—[he said this so] that he could rescue him from them and return him [safely] to his father.
then they took him and threw him into the pit. Now the pit was empty; there was no water in it.
Now Reuben [unaware of what had happened] returned to the pit, and [to his great alarm found that] Joseph was not in the pit; so he tore his clothes [in deep sorrow].
