KJV:

1 Moreover, when ye shall divide by lot the land for inheritance, ye shall offer an oblation unto the LORD, an holy portion of the land: the length shall be the length of five and twenty thousand reeds, and the breadth shall be ten thousand. This shall be holy in all the borders thereof round about.

NASB:

1 "And when you divide by lot the land for inheritance, you shall offer an allotment to the LORD, a holy portion of the land; the length shall be the length of 25,000 cubits, and the width shall be 20,000. It shall be holy within all its boundary round about.
