Ten miracles were wrought for our forefathers in Egypt, and ten at the Red Sea. Ten plagues did the Holy One—blessed be He!—inflict on the Egyptians in Egypt, and ten at the sea. Ten times did our ancestors tempt God in the wilderness, as it is said (Num. xiv. 22), "And have tempted me now these ten times, and have not hearkened to my voice."
Ibid., mish. 5, 6, 7.
Ten times did God test our forefathers, and they were not so much as once found to be perfect.
Avoth d'Rab. Nathan, chap. 34.
Ten times the Shechinah came down unto the world:—At the garden of Eden (Gen. iii. 8); at the time of the Tower (Gen. xi. 5); at Sodom (Gen. xviii. 21); in Egypt (Exod. iii. 8); at the Red Sea (Ps. xviii. 9); on Mount Sinai (Exod. xix. 20); into the Temple (Ezek. xliv. 2); in the pillar of cloud (Num. xi. 25). It will descend in the days of Gog and Magog, for it is said (Zech. xiv. 4), "And His feet shall stand in that day upon the Mount of Olives" (the tenth is omitted in the original).
Ibid.
The Shechinah made ten gradual ascents in passing from place to place:—From the cover of the ark to the cherub (2 Sam. xxii. 11); thence to the threshold of the house (Ezek. ix. 3); thence to the cherubim (Ezek. x. 18); thence to the roof of the Temple (Prov. xxi. 9); thence to the wall of the court (Amos vii. 7); thence to the altar (Amos ix. 1); thence to the city (Micah vi. 9); thence to the mount (Ezek. xi. 23); thence to the wilderness (Prov. xxi. 9); whence the Shechinah went up, as it is said (Hosea v. 15), "I will go and return to my place."
