1 Kings 22:1 - John Gill's Exposition of the Entire Bible

And they continued three years without war between Syria and Israel. From the time that Benhadad made a covenant with Ahab; not three full years, but part of them: it was threatened by Elijah from the Lord, that Ahab's life should go for Benhadad's, because he had let him, go, 1 Kings 22:42, but because of his humiliation, as is thought by Ben Gersom and others, it was respited for those three years; and now an opportunity and occasion would be given for the fulfilment of what was threatened.
