Who first said A man's word is his bond?

The phrase "A man's Word is his bond" is often attributed to the English playwright William Shakespeare, particularly in his play "The Merchant of Venice" (circa 1596). However, the exact Wording does not appear in Shakespeare's texts. The phrase encapsulates the idea of trust and integrity in personal commitments, reflecting a long-standing cultural value regarding honesty and reliability. Over time, it has become a common proverb, symbolizing moral obligation and personal integrity.
