Rashi on Deuteronomy 1:13/רש"י על דברים א׳:י״ג

1הבו לכם means GET YOURSELVES READY for the matter (cf. Rashi on Genesis 11:3).

2אנשים MEN — But would it enter your mind that he would take women? Why then does it state here men? It means that he should take righteous, desirable men (cf. Sifrei Devarim 13:2).

3חכמים ונבנים WISE AND UNDERSTANDING [MEN] — i.e. men who can understand a matter out of (i.e. by comparison with) another matter. — This is what Arius asked R. Jose: what is the difference between wise men and understanding men? A wise man is like a rich money changer: when people bring him dinars to examine (to value) he examines them; and when they do not bring to him, he sits and does nothing (he does not go out to seek any). An understanding man, however, is like a merchant money changer: when they bring him coins to examine, he examines them; and when they do not bring to him, he goes about and brings of his own money (i.e. he himself buys coins) (cf. Sifrei Devarim 13:3).

4וידעים לשבטיכם AND [MEN] KNOWN AMONGST YOUR TRIBES — i.e. men who are known to you. For if he were to come before me wrapped in his robe, “I" would not know who he is and of what tribe he is, and whether he is fitted for the office: but you know him for you have been brought up with him. On this account it states: known amongst your tribes (Sifrei Devarim 13:4).

5בראשיכם [AND I WILL PLACE THEM] AT YOUR HEADS — as chiefs and persons honoured by you., i.e., that ye should pay them respect and reverence.

6ואשמם — This word lacks the letter י (after the ש: our editions, however, have it): this teaches that Israel's transgressions (אשם) are placed upon the heads of their judges, because it is their duty to prevent them from sinning, and to direct them into the right path (Sifrei Devarim 13:6).
