needle

Concise Bible Dictionary:

 
Needle's eye—Jerusalem (El-Kouds), approach to the city. Jaffa Gate closed, showing 'Needle's Eye.'
This occurs in the gospels in the saying that it is easier for a camel to pass through the eye of a needle than for a rich man to enter into the kingdom of heaven (Matt. 19:2424And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God. (Matthew 19:24); Mark 10:2525It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God. (Mark 10:25); Luke 18:2525For it is easier for a camel to go through a needle's eye, than for a rich man to enter into the kingdom of God. (Luke 18:25)). Efforts have been made to refer “the eye of a needle” to a wicket gate, through which a camel can pass, but only with great difficulty; but the Lord speaks of it as something “impossible” except to God. Doubtless a common needle was alluded to. The rabbis had a similar proverb concerning the elephant. Needles have been found in the Egyptian tombs, made of bronze about three inches in length.
