Mishneh Torah, Sabbath
We may only measure with a rope of fifty ells—not less and not more—and with a rope of flax, so that it will not stretch too much. [If] one reached a vale [while measuring]: If it is [no more than] fifty ells, such that he he can subsume it with the measure of the rope, he subsumes it (he surveys it according to the measure of the rope stretched flatly over it). And that is so long as its depth is less than four thousand ells.
