Deuteronomy 7:9 contains an example where the number one is multiplied 1000
times.
“9 Know therefore that the LORD thy God, he is God, the faithful God, which
keepeth covenant and mercy with them that love him and keep his commandments to
a thousand generations;”
In 1Chronicles 16:15, God increased the number one thousand times in the
following example:
“15 Be ye mindful always of his covenant; the word which he commanded to a
thousand generations;”
In Revelation 20:4, the Bible states that the resurrected saints will reign with
Christ for 1000 years:
“4 And I saw thrones, and they sat upon them, and judgment was given unto
them: and I saw the souls of them that were beheaded for the witness of Jesus,
and for the word of God, and which had not worshipped the beast, neither his
image, neither had received his mark upon their foreheads, or in their hands;
and they lived and reigned with Christ a thousand years.”
