It is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God.
Matthew 19:24
The photo above of a similar gate in Nazareth illutrates the eye of the needle gate quite well. You can see that a camel could not pass through the gate unless it first had all its baggage removed and then stooped to get through the gate. (Photo Credit: BiblePictureGallery.com)
