Commentary for Ruth 2:16

And let [some sheaves] fall for her. שֹׁל תָּשֹׁלּוּ =] you should forget; pretend as though you are forgetting.¹⁴The double verb indicates that the action was to be repeated many times. The Targum for שְׁגָגָה [=oversight], is שְׁלוּתָא,¹⁵Bamidbar 15:25. and similarly, “because of this error.”¹⁶II Shmuel 6:7. Another explanation [of שֹׁל תָּשֹׁלּוּ is “let fall”], an expression [as in,] “your olive tree will cast off [= יִשַּׁל [its fruit].”¹⁷Devarim 28:40.

Bundles. Small sheaves, and there is a similar expression in the language of the Mishnah, “[If] he found them [tefillin] tied up in bundles or in packets.”¹⁸Maseches Eruvin 10:1.
