This metaphor was used by Jesus. A rich youth came to him and said he has obeyed all commands. The Jesus said: sell all your riches and give it to the poor. The man went away disappointed. Then Jesus said to his disciples: it is more easier for a Camel to Enter the Eye of a Needle than for a rich man to enter the Kingdom of Heaven. Camel and the Eye of a Needle as an idiom mean something virtually impossible to accomplish. For me to become the President of America is the Camel and the Eye of a Needle. That task is the camel and the eye of a needle.
