The morning is come unto thee. — The word here used is not the usual one for morning. This word occurs elsewhere only in Ezekiel 7:10 and Isaiah 28:5, where it is translated crown. There is much difference of opinion both as to its derivation and its meaning. The most probable sense is circuit — “the circuit of thy sins is finished, and the end is come upon thee.”
The sounding again of the mountains. — This is again a peculiar word, occurring only here; but it is nearly like and probably has the same meaning as the word in Isaiah 16:10; Jeremiah 25:10, denoting the joyous sounds of the people, especially at harvest-time, filling the land and echoing back from the mountains. Instead of this shall be the tumult (rather the trouble) of the day of war. (See the opposite contrast in Exodus 32:17-18.)
