Isaiah 55:12
For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands.
For ye shall go out with joy, and be led forth with peace,.... Though these words may literally respect the Jews' return from captivity to their own land, attended with joy and peace; as the preceding verse may respect the word of promise concerning it; as it is interpreted by the Targum,
"for with joy shall ye go out from among the people, and with peace shall ye be brought to your own land;''
yet they may be spiritually applied to the conversion of men, in consequence of the word being made effectual, of which the deliverance from the Babylonish thraldom was a type; when men "go out" of a state of bondage to sin, Satan, and the law; out of a state of darkness and ignorance; out of the pit of nature's misery and distress; out of themselves and their own righteousness; out of their own sinful ways, and from among the men of the world: and though here is a divine power exerted in all this, yet they go out freely, being led by the Spirit of God; who takes them by the hand as it were, and leads them in ways before unknown to them; he leads them to Christ, his person, fulness, blood, and righteousness; to the house of God, and to the ordinances of it; and from one degree of grace to another, till he brings them to glory: all which is attended with "joy and peace" to themselves; finding themselves released from bondage, in a state of light and comfort, out of the horrible pit, and on a rock; brought to Christ, and clothed with his righteousness; to the angels in heaven, who rejoice over every sinner that repenteth; to the ministers of the Gospel, who are the instruments of their conversion; and to all the saints into whose fellowship they are brought; which joy is further illustrated by the following strong figures:
the mountains and the hills shall break forth before you into singing; or the people that dwell upon them: and all the trees of the field shall clap their hands; or clap with their branches; as the Targum, the tops of them, being moved with gentle breezes of wind, bow themselves, and the branches intertwining and clasping each other like hands and arms. Kimchi observes, that "mountains and hills" may signify the kings of the nations; and "the trees of the field" the people rejoicing at the deliverance of the Jews, as they pass along: it may be as well applied to the ministers of the word, and common believers rejoicing at the conversion of sinners, in whom as wonderful a change is wrought, as in the following cases. Vitringa interprets this of the apostles and ministers of the word going forth into the Gentile world, attended with joy in themselves, and among the converts there.
