Who said own flesh and in the merchant ot Venice?

The phrase "in the Merchant of Venice" is inaccurate in this context. Instead, the quote "own flesh and blood" originated in the well-known play "Hamlet" written by William Shakespeare. The phrase is used in Act 2, Scene 2, when Hamlet talks to his mother Queen Gertrude about her marriage with Claudius. Hamlet expresses sorrow and disappointment while addressing the issue of betrayal by his own family members, using the expression "own flesh and blood."
