Make bright the arrows. — Better, Sharpen, the “polishing” or “making bright” being as the means to that end.
Gather the shields. — Literally, fill the shields, i.e., arm yourselves with them, The large shields of the Persian soldiers covered the whole body, and the man literally filled them. The LXX. and Vulgate agree in rendering the noun “quivers” instead of “shields,” but this would seem to have been a conjecture rising out of a wish to connect the two clauses. The rendering of the Authorised version agrees with the use of the word in Song Song of Solomon 4:4; Ezekiel 27:11; 2 Kings 11:10. Some critics interpret the words as meaning “fill the shields with oil,” as parallel to “sharpen the arrows,” and agreeing with “anoint the shield” in Isaiah 21:5.
Of the kings of the Medes. — As with the Greeks in their use of the terms Medise and Medism, so with the Hebrews the Medes are more prominent than the Persians in the work of destruction (comp. Isaiah 13:17). The “kings” are the chieftains of tribes more or less independent, but owning the suzerainty of the Persian king. It is noticeable that the ruler of Babylon, after its capture by Cyrus, in Daniel 5:31, is “Darius the Median,” and that he is called a “king.”
