Ps 82:5

“"Since they have imagined with one consent; together against Thee have they disposed a testament" (ver. 5): as though they could be the stronger. In fact, "a testament" is a name given in the Scriptures not only to that which is of no avail till the death of the testators, but every convenant and decree they used to call a testament. For Laban and Jacob made a testament, which was certainly to have force between the living; and such cases without number are read in the words of God. Then he begins to make mention of the enemies of Christ, under certain proper names of nations; the interpretation of which names sufficiently indicates what he would have to be understood. For by such names are most suitably figured the enemies of the truth. "Idumaeans," for instance, are interpreted either "men of blood," or "of earth." "Ismaelites," are "obedient to themselves," and therefore not to God, but to themselves. "Moab," "from the father;" which in a bad sense has no better explanation, than by considering it so connected with the actual history, that Lot, a father, by the illicit intercourse procured by his daughter, begat him; since it was from that very circumstance he was so named. Good, however, was his father, but as "the Law is good if one use it lawfully," not impurely and unlawfully. "Hagarens," proselytes, that is strangers, by which name also are signified, among the enemies of God's people, not those who become citizens, but those who persevere in a foreign and alien mind, and when an opportunity of doing harm occurs, show themselves. "Gebal," "a vain valley," that is, humble in pretence. "Amon," "an unquiet people," or "a people of sadness." "Amalech," "a people licking;" whence elsewhere it is said, "and his enemies shall lick the earth." The "alien race," though by their very name in Latin, they sufficiently show themselves to be aliens, and for this cause of course enemies, yet in the Hebrew are called "Philistines," which is explained, "falling from drink," as of persons made drunken by worldly luxury. "Tyre" in Hebrew is called Sor; which whether it be interpreted straitness or tribulation, must be taken in the case of these enemies of God's people in that sense, of which the Apostle speaks, "Tribulation and straitness on every soul of man that doeth evil." All these are thus enumerated in the Psalms: "The tabernacles of the Edomites, Ishmaelites, Moab and the Hagarenes, Gebal, and Amon, and Amalech, and the Philistines with those who inhabit Tyre."”

“Instead of לב אחד, Ch1 12:38, it is deliberant corde unâ, inasmuch as יחדּו on the one hand gives intensity to the reciprocal signification of the verb, and on the other lends the adjectival notion to לב. Of the confederate peoples the chronicler (2 Chr. 20) mentions the Moabites, the Ammonites, the inhabitants of Mount Ser, and the Me(unim, instead of which Josephus, Antiq. ix. 1. 2, says: a great body of Arabians. This crowd of peoples comes from the other side of the Dead Sea, מאדם (as it is to be read in Psa 83:2 in the chronicler instead of מארם, cf. on Psa 60:2); the territory of Edom, which is mentioned first by the poet, was therefore the rendezvous. The tents of Edom and of the Ishmaelites are (cf. Arab. ahl, people) the people themselves who live in tents. Moreover, too, the poet ranges the hostile nations according to their geographical position. The seven first named from Edom to Amalek, which still existed at the time of the psalmist (for the final destruction of the Amalekites by the Simeonites, Ch1 4:42., falls at an indeterminate period prior to the Exile), are those out of the regions east and south-east of the Dead Sea. According to Gen 25:18, the Ishmaelites had spread from Higz through the peninsula of Sinai beyond the eastern and southern deserts as far up as the countries under the dominion of Assyria. The Hagarenes dwelt in tents from the Persian Gulf as far as the east of Gilead (Ch1 5:10) towards the Euphrates. גּבל, Arab. jbâl, is the name of the people inhabiting the mountains situated in the south of the Dead Sea, that is to say, the northern Seritish mountains. Both Gebl and also, as it appears, the Amalek intended here according to Gen 36:12 (cf. Josephus, Antiq. ii. 1. 2: Ἀμαληκῖτις, a part of Idumaea), belong to the wide circuit of Edom. Then follow the Philistines and Phoenicians, the two nations of the coast of the Mediterranean, which also appear in Amo 1:1-15 (cf. Joel 3) as making common cause with the Edomites against Israel. Finally Asshur, the nation of the distant north-east, here not as yet appearing as a principal power, but strengthening (vid., concerning זרוע, an arm = assistance, succour, Gesenius, Thesaurus, p. 433b) the sons of Lot, i.e., the Moabites and Ammonites, with whom the enterprise started, and forming a powerful reserve for them. The music bursts forth angrily at the close of this enumeration, and imprecations discharge themselves in the following strophe.”
