Goat in the Wilderness

The origin of the "scapegoat" can be found in this week's parasha. In Levitus 16:21, Aaron confesses all of the peoples' sins "on the head of a goat." The animal is then set free in the wilderness. As I tried to picture this ritual, I realized that the Bible is very stingy with description.

There goat is in the text, but no scrub.
No creosote bush clings to the crust of the dunes.
No pale crag martin nests in the cliffs. No cliffs,
orange, gray, or parched. No darkling beetle
with the scavenged barley from their sacks
scuttles like a thief across their path.
No metaphor of any kind. Their eyes
can’t make connections in this wilderness,
which is not like Egypt. They sigh for leeks,
for fish, while a G-d they hardly know
speaks his sentences: “Do not uncover."
"Do not lie down.” It is an abstract world
they will inherit: a Land they’ll never reach,
a holy word, a G-d who turns the face
He does not have toward them and away.
