How is a moderately steep hill (rising 10 handbreadths in 5 cubits) measured for the techum?
Synopsis
A hill that rises 10 handbreadths in 5 cubits of horizontal distance is measured using the 'havla'ah' (spanning) technique with a 50-cubit rope, using upright poles. If the span is less than 50 cubits, the slope is absorbed entirely; if wider, it is measured with a 4-cubit rope using the stepping (kidor) method.
