Comentario citado sobre Deuteronómio 19:3

ומתקנים את הדרכים ואת הרחובות – and the marketplaces that were ruined vy rains during the days of he winter, we repair them for the those who come up on Pilgrimage (i.e., at Passover, Shavuot and Sukkot). But there are those who interpret – because of the killers who murder people unintentionally that are able to flee from before the blood avenger as it is written (Deuteronomy 19:3): “You shall survey the distances, [and divide into three parts the territory of the country hat the LORD your God has allotted to you, so that any manslayer may have a place to flee to].”

And direct roads were made leading from one to the other, as it says, “You shall prepare the way and divide the borders of your land into three parts” (Deut. 19:3). Roads were to be made leading to the cities of refuge so that the manslayer would not have a difficult time finding his way. Remember that if the blood avenger found him before he arrived at the city of refuge he could kill him without incurring penalty.

therefore, He leads sinners on the road of repentance. Another explanation: He leads sinners, meaning murderers [who flee to the cities of refuge], as it is said (in Deut. 19:3): “You shall prepare for yourself the road, etc.” Refuge, refuge,” was written at the crossroads, etc., as is stated in Makkoth, chapter 2 (10b).

For three days. You shall triple the days, and then you should go down very much, i.e., when the third day arrives,¹⁴Others translate וְשִׁלַשְׁתָּ as “mark three times” [the spot where to hide] to avoid any misunderstanding. The same expression [וְשִׁלַשְׁתָּ], is used to tell the Bnei Yisroel to mark the borders of the land into three parts in Devarim 19:3. you should go down into a secret place, and hide very well, because they will seek you then. And you shall come to this secret place, where you are hiding today, which is a work day.¹⁵I.e., the day after Rosh Chodesh is described as a work day in comparison to Rosh Chodesh which is considered a holiday because they did not engage in their usual work. And similarly Targum Yonoson renders, on a week day, for he hid on that day, as it is stated, 'and Dovid hid in the field,'¹⁶Below verse 24. and immediately, 'it was the New Moon'¹⁷Ibid. on the next day.
