From the Bible
Camel to go through the Eye of a Needle
When Jesus was talking to the Pharisees and the Sadducees he made a caustic remark that it is easier for a Camel to go through the Eye of Needle than for you to go to heaven. Camel to go through the eye of a needle is a virtually impossible task to achieve. For me to become the President of America is like a Camel entering through the eye of a needle.
From the Fish Mouth
When Jesus was questioned about paying the temple tax, he replied to his disciple Peter to get a coin which was wedged in the fish mouth. And Jesus famously told: Give unto Caesar what is his and give unto me what is mine. From the Fish Mouth as an idiom means getting a financial blessing from God. Yes God let me get a bounty from the fish mouth.
