C. F. Keil and Franz Delitzsch on 2 Chronicles 32:9

2Ch 32:9 The advance of an Assyrian army against Jerusalem, and the attempts of Sennacherib’s generals to induce the population of the capital to submit by persuasive and threatening speeches, are very breifly narrated, in comparison with 2 Kings 18:17-36. In 2Ch 32:9, neither the names of the Assyrian generals, nor the names of Hezekiah’s ambassadors with whom they treated, are given; nor is the place where the negotiation was carried on mentioned. עבדיו, his servants, Sennacherib’s generals. על־לך, while he himself lay near (or against) Lachish, and all the army of his kingdom with him. ממשׁלתּו, his dominion, i.e., army of his kingdom; cf. Jer 34:1.
