Israelites were taking the road to the Red sea
to go around the land of Edom.
However, as always, Israelites grew impatient against God and Moses.
They began to grumble.
"Why have you brought us out of Egypt?"
"There is nothing to eat and nothing to drink!"
"We're sick of eathing this manna everyday!"
and God sent poisnous snakes among them,
and so many of them were bitten and died.
Then Israelites came to Moses and begged,
"We have sinned by speaking against God,
please, pray to God to take away these snakes."
Moses prayed for the Israelites.
Then God instucted Moses to make a replica of a
poisnous snake and hang it on the top of a pole.
and also commanded Moses to have people look at the snake
for they will be healed simply by looking at it.
Moses did as God instucted him,
and Whenever those who were bitten looked at the bronze snake,
they were healed.
