II Kings 14:28(Chabad translation) says:
"And the rest of the events of Jeroboam and all that he did and his mighty deeds, how he fought, and how he restored Damascus and Hamath to Judah through Israel, are written in the book of the chronicles of the kings of Israel."
The part that always confused me is "he restored Damascus and Hamath to Judah through Israel." There is a Bet prefix to "Yisrael", which appears translated as "in" lots of places elsewhere, but "he restored Damascus and Hamath to Judah in Israel" doesn't make it any clearer to me.
Both Damascus and Hamath bordered Israel, not Judah --- so what does this phrase mean? Israel was almost constantly fighting with the Arameans until the Assyrians put an end to it by overrunning the area, but Damascus and Hamath are never tributary to Judah(both only to David's United Kingdom, and Damascus intermittently only to Israel) in Tanack. The only possible meaning I can think of is that by Jeroboam II's fighting and regaining control of the trade routes to them, commerce with Hamath and Damascus was restored to Judah through Israel.
Are there any explanations or commentary on this verse in later literature?
