Charles Ellicott Commentary 2 Chronicles 7:21

"And this house, which is so high, every one that passeth by it shall be astonished, and shall say, Why hath Jehovah done thus unto this land, and to this house?" — 2 Chronicles 7:21 (ASV)

And this house, which is high. — A correction of Kings: “and this house shall be high,” which appears meaningless in the context. But the Syriac (and Arabic) here and in Kings has, “And this house shall be laid waste.” (nehwê hreb); and the Targum of Kings combines both readings as follows: “And this house which is high shall be laid waste.” (y’hê harîb). It appears, therefore, that the original reading of the Hebrew text was, “And this house shall become ruinous heaps.” (‘îyîn, “heaps,” not ‘elyôn, “high”). (Compare Micah 3:12. The mistake is as old as the Septuagint, ὁ οἶκος οὗτος ὁ ὑψηλός.)

Shall be an astonishment to every one that passeth by it. — Every one that passeth by it shall be astonished: πᾶς ὁ διαπορευόμενος αὐτὸν ἐκστήσεται, Septuagint; Syriac, “Every one that passeth by it shall stop and shake his head, and sway with his hand, and say…” Kings adds, “and shall hiss.” (certainly original).
