Isaiah 60:16
Thou shalt also suck the milk of the Gentiles, and shalt suck the breast of kings: and thou shalt know that I the LORD am thy Saviour and thy Redeemer, the mighty One of Jacob. Thou shalt also suck the milk of the Gentiles, and shalt suck the breast of kings: and thou shalt know that I the LORD am thy Saviour and thy Redeemer, the mighty One of Jacob.
Sucking the milk of the Gentiles and the breast of kings means that Zion, or the redeemed, will receive support and supply from the nations and their rulers. The declaration that thou shalt know means that God's people will personally know that the Lord is their Saviour and their Redeemer, the Mighty One of Jacob. Verses 16-19 place this promise in the city of God after victory and inheritance, marked by abundance, peace, righteousness and safety, with improved conditions of gold for brass and silver for iron, officers made peace and exactors righteousness, no more violence or wasting or destruction, walls called Salvation and gates Praise, and the Lord Himself as an everlasting light and glory in place of sun and moon. This assurance of knowing the Lord belongs with His forgiveness and free, full acceptance through Jesus and His merits, in which He blots out transgressions, does not remember sins, and justifies His people.
As part of Isaiah 60, the verse is connected with the church's work of restoration through varied forms of ministry, carrying the gospel message to people in need of truth. As part of Isaiah 60 and 61, the verse is to be studied, heeded and accepted. That call to study, heed and accept applies to leaders in the cause and those connected with institutions, with thorough consecration to God, and involves receiving reproof for neglected duty to warn the people what is truth. The verse will be understood when reformation comes to God's people, when all complaining and every evil work are stopped. Then God manifests His power and appears for the conviction and conversion of souls, and the desired conditions are brought about by workers in the churches laboring together with God to seek and to save that which was lost.
The verse gives inspiration and encouragement to those called to act a part in God's work on earth, calling them to enter new fields and occupy new territory. It calls them to unite in sowing the gospel seed with each doing his appointed work as a specialty, and to move on to new fields after the truth has been preached rather than lingering over churches long established. That work is to be done not trusting in self but pleading for God's power and grace, with Christ and heavenly angels uniting with those who obey.
