Isaiah 61:6
5 “Foreigners will take care of your sheep; foreigners will work in your fields and vineyards. 6 You will be called, ‘the Lord’s priests, servants of our God.’ You will enjoy the wealth of nations and boast about the riches you receive from them. 7 Instead of shame, you will get a double portion; instead of humiliation, they will rejoice over the land they receive. Yes, they will possess a double portion in their land and experience lasting joy. 8 For I, the Lord, love justice and hate robbery and sin. I will repay them because of my faithfulness; I will make a permanent covenant with them.
LXX Isaiah 61:6
5 Aliens shall come, feeding your sheep, and allophyles as plowmen and vinedressers, 6 but you shall be called priests of the Lord, ministers of God; you shall devour the strength of nations, and with their wealth you shall be admired. 7 Thus they shall inherit the land a second time, and everlasting joy shall be above their head. 8 For I am the Lord, who loves righteousness and hates spoils obtained by injustice; I will give them their hard work righteously, and I will make an everlasting covenant with them.
Notes and References
"... Two passages toward the end of Isaiah contain the phrase “wealth of the nations.” Isaiah 61:6 uses it as something Israel is to eat, perhaps conveying the idea that Israel will plunder ('consume') the nations’ riches. The LXX translators, though, chose to render it using its more common gloss ἰσχὺν ('strength') rather than πλοῦτος. Isaiah 66:12 uses the phrase 'glory of the nations', which may be translated as 'wealth of the nations.' The picture, however, is one of foreign wealth flowing toward Jerusalem like a river, not of Gentiles carrying it as tribute. Rather, the Gentiles escort the Jewish remnant, a repatriation which is seen in verse 20 as an act of 'offering'. Therefore, despite the idea of Gentile wealth being destined for Jerusalem, neither passage here pictures that wealth being carried in a pilgrimage as tribute to King Yahweh ..."
