Isaiah 56:7

Even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices shall be accepted upon mine altar; for mine house shall be called an house of prayer for all people.

Even them - (Ephesians 2:11.)

Will I bring to my holy mountain - Jerusalem, the seat of the Lord's throne in His coming Kingdom (; ).

Make them joyful - (.)

Their burnt offerings and their sacrifices - spiritual, of which the literal were types (; ; ).

(Shall be) accepted - (.)

Upon mine altar () - spiritually, the cress of Christ, which sanctifies our sacrifices of prayer and praise.

An house of prayer for all people - or rather, peoples. No longer restricted to one favoured people (; ; ; ). To be fully realized at the second coming (Isaiah 2:2). No longer literal, but spiritual sacrifice, namely, "prayer," shall be offered (; ; ).
