One who says to his slave, “Go out and slaughter the pesach-offering for me,” [if] he slaughtered a kid he may eat [of it, if] he slaugh-tered a lamb he may eat [of it]. [If] he slaughtered [both] a kid and a lamb he must eat of the first.  [If] he forgot what his master told him, what should he do? Let him slaughter a lamb and a kid and say: “If my master told me [to slaughter] a kid, let the kid be his and the lamb mine; and if my master told me [to slaughter] a lamb, let the lamb be his and the kid mine.”  [If] his master forgot what he had told him, both go forth to the place of burning. And they are exempt from participating in [the] second pesach.
