This is one of those Passages where we shake out heads and go “I don’t know”. However all the answers are in old theology books. There is nothing new under the sun. There is always someone in ages passed that knew what the passage meant.
A Song of Ascents.
1 In my distress I cry to the LORD, that he may answer me:
2 “Deliver me, O LORD, from lying lips, from a deceitful tongue.”
3 What shall be given to you? And what more shall be done to you, you deceitful tongue?
4 A warrior’s sharp arrows, with glowing coals of the broom tree!
5 Woe is me, that I sojourn in Meshech, that I dwell among the tents of Kedar!
6 Too long have I had my dwelling among those who hate peace.
7 I am for peace; but when I speak, they are for war!
So where was or is Meshech and what or who are the tents of Kedar?
Meshech is one of the sons of Japheth from whom the Europeans descended [Gen 10:2]. And it never has been a good place for the children of Israel to be in their wanderings. The Crusades, The INQUISITION, the progroms, and constant evictions followed them everywhere the wandered. It wasn’t until Oliver Cromwell in 1699 that they could even be buried in England.
Kedar was a son of Ishmael [Gen 25:13]. The question is why of all the sons of Ishmael this one and not one of the other 11? Because Mohammed was of the Koresh clan and they descended from Kedar. As the RamBam put it “for the Madman and imbecile is of the lineage of the children of Kedar as they readily admit.” Maimonides, “Letter to Yemen” 1:4. The RamBam wrote in Hebrew so the word “Madman” would have been “Meshugana”.
Maimonides saw that this was a prophecy about the subjugation of the Jews to the Arabs because of the teaching of the Meshugana one. That this was because of the Jews sin, and there was noting to do but endure.
Remember, my co-religionists, that on account of the vast number of our sins, God has hurled us in the midst of this people, the Arabs, who have persecuted us severely, and passed baneful and discriminatory legislation against us, as Scripture has forewarned us, “Our enemies themselves shall judge us” (Deuteronomy 32:31). “Letter to Yemen” 1:4
