2:11 Shall be joined - Shall worship the God of Israel. In that day - When Christ shall come in the flesh, and take down the partition wall. Sent me - The Messiah.
2:10-13 Here is a prediction of the coming of Christ in human nature. Many nations in that day would renounce idolatry, and God will own those for his people who join him with purpose of heart. Glorious times are foretold as a prophecy of our Lord's coming and kingdom. God is about to do something unexpected, and very surprising, and to plead his people's cause, which had long seemed neglected. Silently submit to his holy will, and patiently wait the event; assured that God will complete all his work. He will ere long come to judgment, to complete the salvation of his people, and to punish the inhabitants of the earth for their sins.
