He was also told to kill his son as a test, which he was literally in the process of doing when YHVH said, "Nah, J/k, ROFLMAO.."
Also Jews practiced both burnt and blood sacrifices prior to their reformation, and Falashas aka Ethiopian Jews still practice blood sacrifices
Oh, and BTW "burnt" sacrifice is pretty well accepted to be a cooked human offering, kinda like what the Jews were offering up to the golden calf while Moses was on Mt. Sinai, so maybe (you) should learn to read and go fuck yaself while you're at it
