>>22713297>There were multiple gods the Jews/Canaanites worshipped that demanded child sacrifice. Like Ishtar tooIshtar is the ancient Sumerian goddess of sex, love and war and the patron deity of the capital city of Uruk and is not involved in what you are talking about.
Your confusion probably comes from the fact that the name/concept is similar to the Canaanite goddess Asherah (probably inspired by Ishtar/imported to some extent by oral tradition) who was being worshipped alongside Baal and Yahweh during Ahab's reign.
While they almost certainly were sacrificing children to Asherah in Canaan I don't think there is any evidence such things were being done for Ishtar back in ancient Sumeria and Ishtar is unrelated.
