Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God. Matthew 19:24.
“By “camel” here he means not the living thing, the beast of burden, but the thick rope to which sailors tie their anchors. He shows this comparison to be not entirely pointless (as a camel would be), but he makes it an exceedingly difficult matter; in fact, next to impossible.”
Cyril of Alexandria (376-444) in Fragment 219
