Ezekiel 47:3-4

3As the man went eastward with a measuring line in his hand, he measured off a thousand cubits That is, about 1,700 feet or about 530 meters and then led me through water that was ankle-deep. 4He measured off another thousand cubits and led me through water that was knee-deep. He measured off another thousand and led me through water that was up to the waist.
