      again--rather, "yet."
      give place--rather, "stand close to me," namely, in order that we may be the more able to dwell in in the narrow place [HORSLEY]. Compare as to Israel's spiritual children, and the extension of the gospel sphere, Ro 15:19, 24; 2Co 10:14-16. But Isa 49:22 (compare Isa 66:20) shows that her literal children are primarily meant. GESENIUS translates, "Make room."
