'To number bones,' as in Psalm 22:14-18, signifies wanting to dissipate truths by reasonings and false principles. Similarly, 'to number,' as in Isaiah 22:10, signifies falsifying.

A 'number' also signifies the quality of a thing regarding truth. (See Apocalypse Explained 429.)

454. Out of every nation and all tribes, signifies all who are in good in respect to life according to the doctrinals of their religion. This is evident from the signification of "nation," as being those who are in the good (on which see above, n. 175, 331), here those who are in the good of life; also from the signification of "tribes," as being the goods and truths of the church in the whole complex (on which see also above, n. 431. But here, as those who are in the good of life according to their religion are treated of, "tribes" signify the doctrinals of religion that such believe to be truths and goods, and this is what is meant by "tribes" in the Word when such are treated of; while "the tribes of Israel," which were treated of above mean all who are in the genuine truths and goods of the church, and in an abstract sense those truths and goods. So here, "out of every nation and all tribes" signifies all who are in good in respect to life according to the doctrinals of their religion.
