משנה אויף במדבר 7:9

If one carries something out, whether with his right or with his left hand, in his lap or on his shoulder, he is liable, because this the way of the carrying of the children of Kohat (Numbers 7:9). In a backhanded manner, with his foot, in his mouth, with his elbow, in his ear, in his hair, in his belt with its opening downwards, between his belt and his shirt, in the hem of his shirt, in his shoes or sandals, he is not liable, because he has not carried [it] out as people [generally] carry out.
