Isaiah 66:10

“Rejoice ye with Jerusalem, and be glad with her, &c.] The church; she bringing forth so many spiritual children to Christ; just as, when a woman is delivered of a child, her friends and neighbours congratulate her upon it, and rejoice with her on that account; as Elisabeth’s neighbours and relations did, at the birth of John the Baptist, (<420157>Luke 1:57,58), so the church’s friends here are called together to rejoice with her, at the numerous birth and conversion of souls in her, than which nothing is more joyful to the saints; (see <421506>Luke 15:6,9,23,24 <441503> Acts 15:3): all ye that love her; wish her well, and pray for her peace and prosperity; all that love God love his church,…”
