The higher numbers appear frequently to carry the double characters of the numbers which multiplied together produce them. And when it is a number multiplied by itself, the intense value of it will be seen expressed thus.
The 7th year was the year of release, as we have seen, but 7 times 7 brings us to the year of jubilee, with its full and complete deliverance (see Lev. 25).
We saw 10 gerahs given for atonement money by every Israelite, but those who had to be specially redeemed of Israel's firstborn, because they were more in number that the Levites had to give 10 times 10 gerahs = 100, or 5 shekels (Num. 3:47).
Ten is the number of responsibility chiefly as before God, but for the foundation of the tabernacle 100 silver sockets were required. The special and intense thought of responsibility in God's presence is so expressed. Christ Himself is the one foundation, He alone could sustain God's house suitably.
The thickness of the wall of the New Jerusalem is 144 cubits, i.e. 12 x 12 (Rev. 21:17). But the city is the figure of glorified saints in relation to earth, transmitting the light of the glory of God to the nations. For the wall is of jasper, clear as crystal, but earth's jaspers are all opaque. So, the bodies of the saints now are similar, but then they will be fashioned like unto the body of His glory, and as they are seen in such a character in that wall, so its thickness is given accordingly, 12 x 12, a special emphasis put upon their administration of this light of God during the Millennium, to those below who are meant to enjoy it.
The highest numerical expressions in Scripture are the continued multiples of 10, put in the plural form so that they are unlimited. They are "thousand thousands" and "ten thousand times ten thousand" in Dan. 7:10. These are used once again, in Rev. 5:11, where it is literally, "ten thousands times ten thousands and thousands of thousands." In the former passage, the countless hosts are seen as the expression of the dignity and power of their Creator the grandeur of God the mass of His creatures ministered unto Him and stood before Him. It is instructive to see the Holy Ghost bringing these numbers into use but once more. And then employing them to declare the worthiness of the Lamb that had been slain. It is an impressive evidence of the prescriptive title of the Lamb to the supreme place above all created beings. All who in Daniel could be summoned to display the majesty of God the Creator and Judge are, in Rev., introduced to us once again, when redemption has been wrought, to join and say with a loud voice the seven fold worthiness of Him who had wrought it. So was it God's blessed pleasure to reveal His estimate of the Lamb that had been slain. (Observe that in Gen. 24:60, the Hebrew word "millions" is literally "ten thousand" and not more, while also in Num. 10:36, it should be "unto the ten thousands of thousands of Israel.")
