The term "Needle's Eye" often refers to a narrow opening or passage, symbolizing a challenging or difficult situation. In a biblical context, it is famously mentioned in the New Testament as a metaphor for the difficulty of a rich person entering the Kingdom of Heaven. In a more literal sense, a needle's eye is the small hole at the end of a sewing needle through which thread is passed. This tiny opening is essential for sewing and embroidery, highlighting the precision required in these crafts.
