Tosefta untuk Amsal 17:28

[If there are] two [groups] of three [registrants] each, three of four each, four of five each, five of six each, six of seven each, seven of eight each, eight of nine each, [or] nine of ten each [and their Passover offerings got mixed up], they register one person from each and every group, and two from the last group, [and this group] sets aside one Passover offering, and they say, "Whosever Passover offering is this, we withdraw our hands from ours and we register ourselves for his." [If there are] three [groups] of two [registrants] each, four of three each, five of four each, six of five each, seven of six each, eight of seven each, nine of eight each, [or] ten of nine each [and their Passover offerings got mixed up], one person from each and every group withdraws himself [and they form a new group], and they set aside one Passover offering and say, "Whosever Passover offering is this, we withdraw our hands from ours and we register for his," and it comes out that they become attached to [the new group that] they joined, and they leave behind [the group from which they were] uprooted. § [If] he said to them [“If I delay, go and slaughter on my behalf"] or they said to him ["If we delay, go and slaughter on our behalf," and they both slaughtered an animal for a Passover offering] (see Pes. 9:9), they eat from the first [slaughtered animal]. [If] he did not say to them and they did not say to him [the aforementioned declaration, and they both slaughtered an animal], they are not responsible for each other [and they each eat from their own offering]. From this they said, "silence is befitting of the wise, and all the more so of fools." And so too it says (Prov. 17:28), "Even a fool who keeps his silence is considered wise" -- and needless to say a wise person who keeps his silence -- "and one who seals his lips is intelligent."
