Matthew Henry's Concise Commentary

68:29-31 A powerful invitation is given to those that are without, to join the church. Some shall submit from fear; overcome by their consciences, and the checks of Providence, they are brought to make peace with the church. Others will submit willingly, ver. 29,31. There is that beauty and benefit in the service of God, and in the gospel of Christ which went forth from Jerusalem, which is enough to invite sinners out of all nations.
