(6) The proud boast of the preceding verse is repeated here with allusion to the census or birth-register of citizens. (See Ezekiel 13:9; Isaiah 4:3; Psalm 69:28, Note.) No doubt these lists were often produced or appealed to in triumph to mark the superiority of a native of Jerusalem over those born at a distance.

Verse 6. - The Lord shall count, when he writeth up the people; rather, the peoples, (see ver. 4). That this man was born there. He shall enregister every individual among the converted nations as a true citizen of Zion, entitled to all covenant privileges.

87:4-7 The church of Christ is more glorious and excellent than the nations of the earth. In the records of heaven, the meanest of those who are born again stand registered. When God renders to every man according to his works, he shall observe who enjoyed the privileges of his sanctuary. To them much was given, and of them much will be required. Let those that dwell in Zion, mark this, and live up to their profession. Zion's songs shall be sung with joy and triumph. The springs of the joy of a carnal worldling are in wealth and pleasure; but of a gracious soul, in the word of God and prayer. All grace and consolation are derived from Christ, through his ordinances, to the souls of believers.The Lord shall count when he writeth up the people, Not in the Lamb's book of life; for that was written from eternity, Revelation 13:8 but in the writing of the house of Israel, among the living in Jerusalem, and with his righteous ones; which is done at effectual calling, and when admitted members of Gospel churches, whereby they openly appear to be the children of God, and are taken into the list and catalogue of saints; see Ezekiel 13:9 or in the last day, when the Lord will take the number of his people,

and cause them again to pass under the rod of him that telleth them; and will make up his jewels, complete the number of them in conversion, and collect them all together; and his counting and writing them may denote his exact knowledge of them, and his care that he lose none; but this will only concern regenerate persons; the Lord will not count nor make any account of any others, as follows:

that this man was born there; and the man that is born in Zion, even every regenerate man, will be counted and numbered by him, and declared to be his, when he makes a general survey and muster of his saints another day.
