Even those I will bring to My holy mountainAnd make them joyful in My house of prayer.Their burnt offerings and their sacrifices will be acceptable on My altar;For My house will be called a house of prayer for all the peoples.”

“All the flocks of Kedar will be gathered together to you,The rams of Nebaioth will minister to you;They will go up with acceptance on My altar,And I shall glorify My glorious house.
