Mishnah for Oktzin 2:6
בֵּיצָה מְגֻלְגֶּלֶת, עַד שֶׁיָּגוֹס. וּשְׁלוּקָה, עַד שֶׁיְּרַסֵּס. עֶצֶם שֶׁיֶּשׁ בּוֹ מֹחַ, חִבּוּר, עַד שֶׁיְּרַסֵּס. הָרִמּוֹן שֶׁפְּרָדוֹ, חִבּוּר עַד שֶׁיַּקִּישׁ עָלָיו בְּקָנֶה. כַּיּוֹצֵא בוֹ, שְׁלַל הַכּוֹבְסִין וְהַבֶּגֶד שֶׁהוּא תָפוּר בְּכִלְאַיִם, חִבּוּר, עַד שֶׁיַּתְחִיל לְהַתִּיר:
[The shell of] a cooked egg, [with regard to the egg, is considered to be a connection] until one cracks it. That of a hard-boiled egg [is considered to be a connection] until one mashes it. A bone containing marrow in it is considered to be a connection [between the bone and the marrow] until one mashes it. A pomegranate which was separated is considered to be a connection [between the seeds and the peel] until one knocks it with a stick [to loosen the seeds]. Similarly, the loose stitches of launderers [who would stitch pieces of laundry together to prevent them from getting lost] or a garment that had been stitched together with <i>kilayim</i> [the product of forbidden crossbreeding or working of certain animals with one another, planting together certain plants, or interweaving certain fibers] is regarded as a connection until one begins to undo them.
