Ver. 7. Even them will I bring unto my holy mountain] i. e. Into my Church and Church-Aſſemblies. Quaere whether Eunuches and ſtrangers were made partakers of all holy ſervices in the ſecond Temple, according to the letter? Sure we are, that that holy Eunuch. Acts 8. and the reſt of the Gentiles had and ſtill have free admiſſion under the Goſpel.

And will make them joyful in mine houſe of prayer] by their free acceſſe unto me, and all good ſucceſſe in their ſuits. Pray that your joy may be full, Joh. 16.24. Draw water with joy out of this well of ſalvation, Iſa. 12. Rejoyce evermore, and that you may ſo do, Pray without ceaſing, 1 Theſ. 5.16, 17.

Their burnt offerings and their ſacrifices ſhall be accepted upon mine Altar] Their Evangelical Sacrifices of prayer, praiſe, alms, obedience, &c. ſhall be accepted through Chriſt, Heb. 13.10, 15. who is the true altar that ſanctifieth all that is offered on it, Rev. 8.3, 4.

For mine houſe ſhall be called, &c.] See on Mat. 21.13.
