There is to [the law of] the ancestral land an [element of] leniency, as well as an [element of] stringency. How so? Whether one consecrates [a field] in the environs of a town, or whether one consecrates [a field] in the orchards of Sebaste — he gives for the [area of land in which a] chomer of barley may be sown,[1] fifty silver shekels; and for an acquired field, he gives its worth. R’ Eliezer says: It is the same for the ancestral field and for the acquired field. What [then] is the difference between the ancestral field and the acquired field? Only that for the ancestral field he gives a fifth, but for an acquired field he does not give a fifth.
