The Altar

HaShem told the Jews to make a large mizbeyach (altar) out of wood, covered in pure copper. This is where the people would bring animals to sacrifice. The altar had a ramp that led up to the fire at the top, and it had rings on its sides, to hold carrying poles.

The altar was holy, and miracles happened there. For example, even though its place was under the open sky, in the courtyard of the Mishkan, rain never put out its fire. Also, even when the wind blew, the smoke from the altar always rose in a perfectly straight line, right up toward the sky.
