720. That "pairs" signify things relatively profane, is evident from the signification of the number "two." A "pair" or "two" not only signifies marriage (and is, when predicated of the heavenly marriage, a holy number), but it also signifies the same as "six." That is to say, as the six days of labor are related to the seventh day of rest, or the holy day, so is the number "two" related to "three;" and therefore the third day in the Word is taken for the seventh, and involves almost the same, on account of the Lord's resurrection on the third day. And hence the Lord's coming into the world, and in glory, and every coming of the Lord, is described equally by the "seventh" and by the "third" day. For this reason the two days that precede are not holy, but relatively are profane. Thus in Hosea:
Come and let us return unto Jehovah, for He hath wounded, and He will heal us; He hath smitten and He will bind us up. After two days He will revive us; on the third day He will raise us up, and we shall live before Him (Hos. 6:1-2).
And in Zechariah:
It shall come to pass in all the land, saith Jehovah, that two parts therein shall be cut off and die, and the third shall be left therein; and I will bring the third part through the fire, and will refine them as silver is refined (Zech. 13:8-9).
And that silver was most pure when purified seven times appears in Psalm 12:6; from all of which it is plain that as "seven" does not signify seven, but things that are holy, so by "pairs" are signified not pairs, but things relatively profane; and therefore the meaning is not that the unclean beasts, or evil affections, in comparison with the clean beasts, or good affections, were few in the proportion of two to seven, for the evils in man are far more numerous than the goods.
