Isaiah 56:6-8

Young's Literal Translation

⁶ And sons of the stranger, who are joined to Jehovah, To serve Him, and to love the name of Jehovah, To be to Him for servants, Every keeper of the sabbath from polluting it, And those keeping hold on My covenant.

⁷ I have brought them unto My holy mountain, And caused them to rejoice in My house of prayer, Their burnt-offerings and their sacrifices [Are] for a pleasing thing on Mine altar, For My house, `A house of prayer,' Is called for all the peoples.

⁸ An affirmation of the Lord Jehovah, Who is gathering the outcasts of Israel: `Again I gather to him -- to his gathered ones.'
