Jerome : (Verse 15, 16.) Because you were abandoned and hated, with no one to pass by, I will make you a pride for all generations, a joy from generation to generation. You will suck the milk of the nations and nurse at the breast of kings. And you will know that I am the Lord, your Savior and strong Redeemer, Jacob. LXX: Because you were abandoned and hated, with no one to help, I will make you an eternal exultation, a joy for generations to come. And you shall suck the milk of nations, and you shall eat the riches of kings. And you shall know that I am the Lord who saves you, and who redeems you, the God of Jacob. What was previously abandoned and despised, with broken branches because they did not bear fruit, they were broken because there was no one to pass by and provide help there. Concerning them it is said in the psalms: And those who passed by did not say: The Lord's blessing upon you (Ps. 128:8); therefore I will make you an everlasting pride, or a source of joy and gladness for two generations: for the former branches, others inserted from the wild olive tree of nations, which will bring forth fruit contrary to their natural example, not of bitterness, but of sweetness, which they have taken from the root. You will suck the milk of the nations, and the breast of kings you will nurse. We have explained in greater detail the meaning of this place, discussing that verse, 'Your sons shall come from afar, and your daughters shall nurse at your side.' Or according to the Septuagint, you will eat the riches of kings. These riches, according to the Hebrew truth, are the breasts of kings and doctors, by which the infancy of those born in Christ is educated and nourished. When you have sucked and have come to solid food, so that you also eat the riches of kings of this kind, then you will know that I am your Savior, who redeemed you with my blood, or the mighty God of Jacob. — Commentary on Isaiah Procopius of Gaza : Those who are strangers to godliness are said to be cut off and hated and to have no help. But those from the wild olive branch come to take their place and are made to be joined into one people out of each. And in the Savior's power there is made the full number of those being saved, the one city out of both tribes that is called Zion, and to it is the following promise made. Some say that it has been humbled on account of its insubordination against Christ and that yet it will be saved through acknowledging this. And so the words that follow are, "I will place you in eternal gladness and joy for all ages." For this is the hope of immortality in the church of God, the everlasting life and glory and kingdom of heaven, and there is no place for shame. "And you will drink the milk of the nations." This means the ever-new sacramental mystery and the fundamental teaching of those being reborn through faith in Christ. — COMMENTARY ON Isaiah 60:1-22
