Isaiah 49:13
Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the LORD hath comforted his people, and will have mercy upon his afflicted.
Sing, O heavens, and be joyful, O earth,.... Which may be understood of the heavens, and the earth by a personification, a figure usual in Scripture, to express the greatness of the benefit received, and to raise thankfulness and admiration in the hearts of God's people; see Psalms 90:11 or by the heavens may be meant the angels in heaven, who, as they rejoice at the conversion of a single sinner, will much more rejoice at such numerous conversions among Jews and Gentiles, here prophesied of, Luke 15:10 and, by the "earth", the saints on earth, the excellent in it, who have a more immediate concern in, and must be affected with, the case here represented:
and break forth into singing, O mountains; such as are in high office either in the state, as Christian kings and princes, Isaiah 49:23 or in the church, as prophets and apostles, Revelation 18:20. The reason of all this is,
for the LORD hath comforted his people; with the discoveries of his love and grace; by his gracious presence among them; by the coming of Christ unto them in a spiritual way; by sending his Spirit, and renewing the face of things, and reviving his work in the midst of them; by the pure and powerful preaching of the Gospel, and comfortable administration of Gospel ordinances; and by large additions of converts made unto them:
and will have mercy upon his afflicted, or "poor", or "meek" and "humble" ones, as the words {l} may be rendered: the Lord's people is a poor and afflicted people, poor in a temporal and spiritual sense; the church and interest of Christ is in a poor and low condition: the Lord's people are afflicted outwardly and inwardly, and so become meek, and are kept humble; these the Lord, in the latter day, will raise from a low and distressed condition to a more exalted and comfortable one; which will be an instance of his mercy and compassion, and be matter of joy unto them.
