Isaiah 56:6-8

Amplified Bible, Classic Edition

⁶ Also the foreigners who join themselves to the Lord to minister to Him and to love the name of the Lord and to be His servants, everyone who keeps the Sabbath so as not to profane it and who holds fast My covenant [by conscientious obedience]—

⁷ All these I will bring to My holy mountain and make them joyful in My house of prayer. Their burnt offerings and their sacrifices will be accepted on My altar; for My house will be called a house of prayer for all peoples.

⁸ Thus says the Lord God, Who gathers the outcasts of Israel: I will gather yet others to [Israel] besides those already gathered.
