Gird sackcloth - שק sak, sackcloth, a word necessary to the sense, is here lost, but preserved by the Septuagint, MSS. Alex. and Pachom., and 1. D. II., and edit. Ald. and Comp., and the Arabic and Syriac.
Tremble - be troubled - strip you - פשטה peshotah, רגזה regazah, etc. These are infinitives, with a paragogic ה he, according to Schultens, Institut. Ling. Hebr. p. 453, and are to be taken in an imperative sense.
Strip ye, and make ye bare - That is, take off your joyful and splendid apparel, and put on the habiliments of mourning, indicative of a great calamity.
And gird sackcloth - (See the note at Isaiah 3:24).
