John Gill Commentary 2 Chronicles 29:9

"For, lo, our fathers have fallen by the sword, and our sons and our daughters and our wives are in captivity for this." — 2 Chronicles 29:9 (ASV)

For, lo, our fathers have fallen by the sword
Of the kings of Syria and Israel, even great numbers of them, (2 Chronicles 28:5 2 Chronicles 28:6) and our sons and our daughters and our wives are in captivity for this ;
for this idolatry; or they were, though afterwards dismissed, (2 Chronicles 28:8 2 Chronicles 28:15) and some of them were still in captivity, perhaps such as were carried captive by the Edomites, (2 Chronicles 28:17) .
