3,840. The Ramp of the Altar

Hilchos Beis HaBechirah 2:13

The ramp was on the south side of the altar; its dimensions were 32 cubits long by 16 cubits wide (approximately 48’x24’). It took up thirty cubits of ground next to the altar and then covered a cubit of the base and a cubit of the catwalk. There was a small gap between the ramp and the altar where the limbs of the offerings were tossed to the altar. The ramp was one-sixth of a cubit less than nine cubits in height, reaching the height of the woodpile.

Two smaller ramps extended from the main ramp, one of which led to the base and the other to the catwalk. These were separated from the altar by a hairsbreadth. There was a cubby of one cubit by one cubit, called the r’vuvah, on the west side of the ramp. That’s where birds that had been disqualified as sin offerings would be kept until they decomposed and could be burned.
