The dry bones are a picture of the Jews in captivity–scattered and dead. The two sticks represent the reunion of the entire nation of Israel which had divided into northern and Southern Kingdoms after Solomon. The scattered exiles of both Israel and Judah would be released from the “graves” of captivity and one day regathered in their homeland, with the Messiah as their leader. This vision has yet to be fulfilled. Ezekiel probably felt he was speaking to the dead as he preached to the exiles because they rarely responded to his message. But these bones responded! And just as God brought life to the dead bones, he would bring life again to his spiritually dead people.
