2 Reis 16:6

At that time. — Bähr regards this verse as a parenthesis, so that 2 Reis 16:7 is the strict continuation of 2 Reis 16:5, and “At that time” simply assigns this war as the epoch when Judah lost its only harbour and chief emporium — a grave blow to the national prosperity. It is perhaps impossible to weave the various data of Isaiah, Kings, and Chronicles into a single narrative which shall be free from all objection. But it seems probable that, after the successes recorded in 2 Crônicas 28:5, seq., the confederates advanced upon Jerusalem, and that Ahaz despatched his envoys to Tiglath Pileser. The allies soon despaired of a siege, and Pekah fell to ravaging the country, while Rezin pushed on to Elath, determined not to return home without having achieved some permanent success. The approach of Tiglath Pileser compelled the two kings to give up their enterprise, and hasten to defend their own frontiers.

Recovered Elath to Syria... the Syrians. — The words for Syria and Edom, Syrians and Edomties, are very much alike in Hebrew writing, and the Hebrew margin, many MSS., the LXX. and Vulg. read Edomites for Syrians here. If this be correct, we must also restore Edom for Syria, as many critics propose. The meaning then becomes this: Rezin emancipated the Edomites from the yoke of Judah imposed on them by Uzziah (2 Reis 14:22) in order to win their active co-operation against Judah. Bähr, however, prefers the readings of the ordinary text, and supposes that Rezin simply expelled the Jews from Elath, and established there a commercial colony of Syrians.
