require his blood from your hand

The phrase "his blood" represents the life of Ishbosheth. Here "from your hand" represents Rechab and Baanah, the sons of Rimmon the Beerothite, introduced in 2 Samuel 4:5. Alternate translation: "hold you responsible for the death of Ishbosheth" (See: rc://en/ta/man/jit/figs-metonymy)
