Commentary for Kiddushin 33:8

ואימא חמש סלעים מכולהו אי כתיב ריקם לבסוף כדקאמרת השתא דכתיב ריקם ברישא שדי ריקם אצאן ריקם אגורן ריקם איקב

Now, however, that 'empty' is written at the beginning,<span class="x" onmousemove="('comment',' Before the enumeration of the three kinds.');">¹⁰</span> apply [the word] 'empty' to 'flock', 'threshing-floor,' and 'wine-press' individually. But let us learn the meaning of 'empty' from the pilgrimage burnt-offering?<span class="x" onmousemove="('comment',' Lit., 'the burnt offering of appearing' cf. Ex. XXIII, 14, 15: Three times thou shalt keep a feast unto me in the year . . and none shall appear before me empty. This is interpreted in Hag. ');">¹¹</span>
