1 Kings 18:30

And he repaired the altar of the Lord that was broken down On the top of Carmel had been one of the high places where worship was paid to Jehovah, after the manner of the worship in the wilderness, till the place which God had chosen became known and the Temple built there. The custom of worship at such spots was continued for a long time after Solomon's date, and Elijah here treats the altar as a specially sacred erection, to be restored in Jehovah's honour.

The LXX. omits this clause here, but introduces one very similar in 1 Kings 18:32.
