Any [consecrated item] that is fit for [offering upon] the Altar but not for Temple upkeep, [or fit] for Temple upkeep but not for [offering upon] the Altar, [or] neither [fit] for [offering upon] the Altar nor for Temple upkeep, is subject to me’ilah.  How so? [If] one consecrated a pit filled with water, a manure dump filled with manure, a dovecote filled with doves, a tree filled with fruit, [or] a field filled with grasses, both they and their contents are subject to me’ilah. But if one consecrated a pit and it subsequently became filled with water, a manure dump and it subsequently became filled with manure, a dovecote and it subsequently became filled with doves, a tree and it subsequently became filled with fruit, [or] a field and it subsequently became filled with grasses, they are subject to me’ilah but their contents are not subject to me’ilah. These are the words of R’ Yehudah.  R’ Shimon says: [If] one consecrates a field or a tree, both they and their produce are subject to me’ilah because [the produce] is a growth of hekdesh.  The offspring of a maaser animal may not suckle from the maaser animal, and others would [therefore] donate [milk] for this purpose. The offspring of a consecrated animal may not suckle from the consecrated animal, and others would [therefore] donate [milk] for this purpose. Laborers may not eat of the dried figs of hekdesh, and so too, a cow may not eat of the vetch of hekdesh.
