Reference for Shabbat 193:12
ובמאי אילימא במעביר למטה מעשרה הוא דמחייב למעלה מי' לא מחייב והאמר ר' אלעזר המוציא משוי למעלה מעשרה חייב שכן משא בני קהת אלא לאו בזורק ולמטה מעשרה הוא דמחייב למעלה מעשרה לא מחייב ש"מ בקלוטה כמה שהונחה פליגי ש"מ
Said R. Joseph: This question was asked by R. Hisda, and R. Hamnuna solved it for him from this: [If one removes an object] from one private domain, to another and it passes through the street itself, R. Akiba declares [him] liable, while the Sages exempt [him]. Now, since it states, through the street itself, it is obvious that they differ where it is below ten. Now, in which [case]? Shall we say. in the case of one who carries [it] across: is he culpable only when it is below ten, but not when it is above ten? Surely R. Eleazar said: If one carries out a burden above ten [handbreadths from the street level]. he is culpable, for thus was the carrying of the children of Kohath, Hence it must surely refer to throwing. and one is culpable only when it is below ten, but not when it is above ten; this proves that they differ in whether an object caught up is as at rest. This proves it. Now, he [R. Hamnuna] differs from A. Eleazar. For R. Eleazar said: R. Akiba declared [him] culpable even when it is above ten; but as to what is stated, through the street itself,<span class="x" onmousemove="('comment',' Which implies below ten.
