Isaiah 61:3

to appoint unto them that mourn in Zion, to give unto them beauty, an ornamental headdress, the groom's turban, for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness, of distress and discouragement; that they might be called trees of righteousness, the planting of the Lord, that He might be glorified, the fact that the believers have become partakers of His mercy redounding to His praise. It is the Messiah Himself who is speaking here, for so He interprets the passage in His great sermon at Nazareth, Luke 4:18. It is repeatedly stated in Scripture that the Messiah has the Spirit of Jehovah, that He has been anointed with the Holy Ghost without measure. The anointing on the part of Jehovah, however, concerns not merely an acknowledgment and acceptance of Christ's person, but includes the laying of a charge upon Him, giving Him an office to perform. It is Christ's prophetic office which here stands out so plainly, His work of bringing the Gospel to poor sinners. That is the essence of His work, to announce the joyful message, the glorious news of salvation, to all men. God has commissioned Him to bind up the broken in heart, the poor, lost, repentant sinners, to proclaim liberation to those who have been taken captive by sin and Satan, to tell those who are bound that they are to be free, that their prison-doors have been opened, to announce that a year, an endless period, of good pleasure and favor of Jehovah has come, a day in which He will avenge His own wrongs and those of His people upon His enemies. For the purpose of His work is to bring comfort and joy to the mourners, to replace the ashes on their head with the turban and tiara of joy, like that worn by a happy bridegroom, to put on the oil of gladness and adornment after the period of deep mourning, when they were in the power of Satan. Where formerly the spirit of distress and uneasiness ruled, the garment of praise to Jehovah shall be donned. All this will result in making the believers trees of righteousness, characterized by the fruits of righteousness in them which are the result of faith. For all this is not their own doing, a matter of self-righteous glorification, but they are the planting of Jehovah, who lives in them, and it is through His favor and mercy that they will be glorified before Him. Such is the office of the Messiah, Jesus Christ, the Lord.
