Bamah: the name given to Israel's shrine in Ezekiel, coined from the ordinary Hebrew word for a place of sacrifice
Ezekiel 20 is a long review of Israel's disloyalty. God recalls that when he brought the people into the land, they picked out every high hill and every leafy tree and offered their sacrifices there. Then comes this line: what is the shrine you keep going to? And ever since, the text says, its name has been Bamah. The name is not a new word. It is the ordinary Hebrew word for a place of sacrifice (בָּמָה), pinned on the thing as its own name.
The point is sarcasm, and it works by sound. In Hebrew the question word, the word for the shrine, and the phrase for the people who keep coming to it all chime on the same syllable, so the sentence mocks even as it asks. The ancient Greek translators gave up and simply spelled the sound out, and English Bibles do the same today, printing "Bamah" and leaving the joke behind.
Naming something is a way of passing judgment on it. Early in Israel's story this word was neutral and even honorable: Samuel presided over a sacrifice at one of these shrines, and Solomon met God at the great one at Gibeon. By the time of the prophets it had turned into something close to an insult. Here Ezekiel finishes that journey. He lets the shrine's own name stand as the charge against it, so that the verdict is audible in the word itself.
