The narrative in 2 Chr. 20:1-30 is entirely additional to Kings; in 2Ch 20:31-37, it runs parallel with 1Ki 22:41-49.
The new court - In Solomon’s Temple there were two courts. One of these had probably been renovated by Jehoshaphat or by his father, Asa 2Ch 15:8, and was known as “the new court.”
Jehoshaphat’s appeal is threefold:
(1) to God omnipotent 2Ch 20:6;
(2) to “our God;”
(3) the God especially “of this house” the temple.
Abraham thy friend - Historically, this is the first use of this remarkable expression, afterward repeated (marginal references). The ground of the expression is to be found principally in Gen 18:23-33, where Abraham spoke with God as a man with his friend (compare Exo 33:11).
The appeal recalls Solomon’s prayer (marginal references), which God had formally accepted by sending down fire from heaven to consume the accompanying offering.
The Maonites of 2Ch 20:1 are here, and in 2Ch 20:22-23, called the “children” or inhabitants “of mount Seir.” Hence, we may gather that they were a tribe of Edomites, the inhabitants, probably of a city Maon (now Ma’an) on the eastern side of the Wady el-Arabah.
The prophet uses words familiar to the people, and connected with several great deliverances (see the marginal references).
By the “cliff (or, rather - as in the margin - ascent) of Ziz,” we must understand the mountain path which leads up from Engedi across the elevated tract still known as El-Husasah, in the direction of Tekoa 2Ch 20:20.
At the end of the brook - Rather, “at the end of the gulley,” or dry torrent-course. No name like Jeruel has been as yet found in this district.
Tekoa (2Sa 14:2 note) lay on the borders of the desert which skirts the highlands of Judaea toward the east. The town was built on a hill of a considerable height.
Praise the beauty of holiness - Some render, “in the beauty of holiness” - i. e. in rich apparel and ornaments suitable to a holy occasion. Compare Psa 29:2.
The Lord set ambushments - These liers in wait have been regarded as angels employed by God to confuse the host and cause its destruction, so that the Moabites and Ammonites first united to destroy the Edomites, and then turned upon each other.
The march of Judah from Jerusalem would take five or six hours. By the time they reached the watch-towers in the wilderness of Jeruel all was over.
Riches with the dead bodies - Several manuscripts give another reading: “riches, and garments.”
The valley of Berachah - Probably, the Wady Bereikut, which lies at a short distance from Tekoa toward the northwest.
The latter clause of this verse helps to reconcile the first clause with the statement that Jehoshaphat “took away the high places” (see 2Ch 15:17 note).
After this - Jehoshaphat’s history had been formally completed 2Ch 20:34. Consequently we can lay no stress on the note of time contained in the words “after this,” which are detached from the context to which they originally referred. On the history 2Ch 20:35-37, see marginal references and notes.
