Amarna letter EA 287, titled: "A Very Serious Crime," is a tall, finely-inscribed clay tablet letter, approximately 8 in tall, from Abdi-Heba the mayor/ruler of Jerusalem, of the mid 14th century BC Amarna letters. The scribe of his six letters to Egypt were penned by the "Jerusalem scribe"; EA 287 is a moderately long, and involved letter. The Amarna letters, about 300, numbered up to EA 382, are a mid 14th century BC, about 1350 BC and 20–25 years later, correspondence. The initial corpus of letters were found at Akhenaten's city Akhetaten, in the floor of the Bureau of Correspondence of Pharaoh; others were later found, adding to the body of letters.

Abdi-Ḫeba was a local chieftain of Jerusalem during the Amarna period. Egyptian documents have him deny he was a mayor (ḫazānu) and assert he is a soldier (we'w), the implication being he was the son of a local chief sent to Egypt to receive military training there.
