Deuteronomy 19:1-3

Young's Literal Translation

19 `When Jehovah thy God doth cut off the nations, whose land Jehovah thy God is giving to thee, and thou hast succeeded them, and dwelt in their cities, and in their houses,

² three cities thou dost separate for thee in the midst of thy land which Jehovah thy God is giving to thee to possess it.

³ Thou dost prepare for thee the way, and hast divided into three parts the border of thy land which Jehovah thy God doth cause thee to inherit, and it hath been for the fleeing thither of every man-slayer.
