Woe is me - My lot is a sad and pitiable one, that I am compelled to live in this manner, and to be exposed thus to malignant reproaches. It is like living in Mesech or in Kedar.
That I sojourn - The word used here does not denote a permanent abode, but it usually refers to a temporary lodging, as when one is a traveler, a pilgrim, a stranger, and is under a necessity of passing a night in a strange land on his way to the place of his destination. The trouble or discomfort here referred to is not that which would result from having his home there, or abiding there permanently, but of feeling that he was a stranger, and would be exposed to all the evils and inconveniences of a stranger among such a people. A man who resided in a place permanently might be subject to fewer inconveniences than if he were merely a temporary lodger among strangers.
In Mesech - The Septuagint and Vulgate render this, “that my sojourning is protracted.” The Hebrew word - משׁך meshek - means, properly “drawing,” as of seed “scattered regularly along the furrows” Psalms 126:6; and then possession, Job 28:18. The people of Meshech or the Moschi, were a barbarous race inhabiting the Moschian regions between Iberia, Armenia, and Colchis. Meshech was a son of Japheth, Genesis 10:2; 1 Chronicles 1:5. The name is connected commonly with “Tubal,” Ezekiel 27:13 : “Tubal and Meshech they were thy merchants.” Ezekiel 39:1 : “I am against ... the chief prince of Meshech and Tubal,” Herodotus (iii. 94; vii. 78) connects them with the Tibarenes. The idea here is, that they were a barbarous, savage, uncivilized people. They dwelt outside of Palestine, beyond what were regarded as the borders of civilization; and the word seems to have had a signification similar to the names Goths, Vandals, Turks, Tartars, Cossacks, in later times. It is not known that they were particularly remarkable for slander or calumny; but the meaning is that they were barbarous and savage - and to dwell among slanderers and revilers seemed to the psalmist to be like dwelling among a people who were strangers to all the rules and principles of civilized society.
That I dwell in the tents of Kedar - The word Kedar means properly dark skin, a darkskinned man. Kedar was a son of Ishmael Genesis 25:13, and hence, the name was given to an Arabian tribe descended from him, Isaiah 42:11; Isaiah 60:7; Jeremiah 49:28. The idea here also is, that to dwell among slanderers was like dwelling among barbarians and savages.
