'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

There are only a couple of references in the Writings to "close" used as a verb, and both stem from Amos 9:11, which talks about closing the "breaches" in the "tent of David." In that case "close" means removing false ideas so that something can be restored. It seems likely that "close" has a similar meaning in similar uses.
