Responsa for Shabbat 183:4

איפוך ביד חייב והתנן פשט בעל הבית את ידו לחוץ ונטל העני מתוכה או שנתן לתוכה והכניס שניהן פטורין התם למעלה מג' הכא למטה מג':

if in a vessel, he is culpable?<span class="x" onmousemove="('comment',' [It was known to the retractors of the Talmud that this controversy took place after Abaye and Raba had retracted (Tosaf.)]; ');">¹⁰</span> — Reverse it. 'If in his hand, he is culpable'? But we learnt: If the master stretches his hand without and the poor man takes [an object] from it, or places [an article] therein and he carries it inside, both are exempt? — There it is above three [handbreadths],<span class="x" onmousemove="('comment',' And the exemption is because the same person did not effect both the removal and the depositing, not because of the tie of the body. ');">¹¹</span> but here it is below three.<span class="x" onmousemove="('comment',' So that it is technically at rest; Cf. p. 12, n. 6. ');">¹²</span>
