רְחָבָה, כְּדֵי לְקַבֵּל אָרִיחַ, וּבְרִיאָה, כְּדֵי לְקַבֵּל אָרִיחַ. רַבִּי יְהוּדָה אוֹמֵר, רְחָבָה אַף עַל פִּי שֶׁאֵין בְּרִיאָה:

(The korah must be) wide enough to receive an ariach and strong enough to receive an ariach [i.e., to support its weight without breaking. And this is the halachah.] R. Yehudah says: Wide enough, even if it is not strong enough.
