Rashi on Deuteronomy 1:16/רש"י על דברים א׳:ט״ז

1ואצוה את שפטיכם AND I COMMANDED YOUR JUDGES — I said to them: be deliberate in judgment: if a certain point of law comes before you once, twice, three times, do not say, "This point of law has already come before me several times”, but discuss it well on that occasion also (Sifrei Devarim 16:1).

2בעת ההוא [AND I COMMANDED YOUR JUDGES] AT THAT TIME — As soon as I appointed them, I said to them, "It is not now as heretofore: heretofore you were your own masters (lit., under your own control), now you are in the service of the Community!” (Sifrei Devarim 16:2).

3שמע — This grammatical form expresses constant doing: oyant in old French, be hearing, just as זכור and שמור (see Rashi on Numbers 25:17).

4ובין גרו AND BETWEEN HIS גר — this is his opponent in the lawsuit who merely heaps up (אוגר) words against him. Another explanation of AND BETWEEN HIS גר — also in a matter concerning a dwelling house (גור = to dwell), — in the division of property amongst brothers, even if it be a dispute about an oven and a kitchen range (cf. Sifrei Devarim 16:8-9; Sanhedrin 7b).
