תָּכִ֣ין לְךָ֮ הַדֶּרֶךְ֒ וְשִׁלַּשְׁתָּ֙ אֶת־גְּב֣וּל אַרְצְךָ֔ אֲשֶׁ֥ר יַנְחִֽילְךָ֖ יְהוָ֣ה אֱלֹהֶ֑יךָ וְהָיָ֕ה לָנ֥וּס שָׁ֖מָּה כָּל־רֹצֵֽחַ׃
Thou shalt prepare thee the way, and divide the borders of thy land, which the LORD thy God causeth thee to inherit, into three parts, that every manslayer may flee thither.
Targum Jonathan on Deuteronomy
You shall prepare a high road, and divide your limit which the Lord your God bestoweth upon you, that any manslayer may flee thither.
