Shakespeare makes allusion to this in Richard II:
`It is as hard to some, as for a camel
To thread the postern of a needle's eye.'
Evidently he understood it not to mean a literal needle but the Needle Gate, so called because it was so narrow and difficult to pass through.
The word Luke, the beloved physician, uses in his Gospel record for a 'needle' is different from that the other Synoptics use. Luke uses the word for a surgeon's needle. We infer, therefore, that our Lord meant an ordinary needle used for sewing.
(Mark 10. 25; Luke 18. 25)
