Reference for Shevuot 80:2

טעמא דכלים וקרקעות דקרקע לאו בת שבועה היא הא כלים וכלים דומיא דכלים וקרקעות חייב

- [No!] The same rule applies: even in the case of vessels and vessels he is also exempt; and the reason it states vessels and lands is because it wishes to teach us that if he admits a portion of the vessels, he is liable also for the lands. Wh does he [intend to] teach us [thereby]?
