Daniel 10:6

“His body also was like the beryl, etc.] That is, that part of it which was not covered with the linen garment, and was seen, was like such a precious stone, said to be of an azure and sky colour, signifying he was the Lord from heaven; though, according to its name, it should be of a sea colour, greenish; and so, according to some, the beryl is. Cocceius thinks the sardonyx is meant, which is of a flesh colour, and so more fit to express the comeliness of a human body; the beryl, being of a different colour, seems not so apt to set forth the agreeable colour of a man. Brauniusf470 is of opinion that the chrysolite is meant, a stone of a golden colour; and takes the sense to be, that such was…”

“His body also was like the beryl - There is a very striking resemblance between the description here given and that of the Saviour as he appeared to John in Patmos, Revelation 1:13-16. See the notes at that passage. It contains, however, no description of the appearance of the body. “Beryl” is “a mineral of great hardness, occurring in green and bluish-green six-sided prisms. It is identical with the emerald, except that the latter has a purer and richer color. “ - Dana, in Webster’s Dictionary.

This was…”

“His body shone like תּרשׁישׁ, i.e., the chrysolite of the Old and the topaz of the New Testament (see under Eze 1:16); his countenance had the appearance of lightning, his eyes as lamps of fire, his arms and the place of his feet like the sight of polished brass (קלל, see under Eze 1:7).מרגּלות, place of the feet, does not stand for feet, but denotes that part of the human frame where the feet are; and the word indicates that not the feet alone, but the under parts of the body shone like burnished brass. The voice of his words, i.e., the sound of his speaking, was like המון קול, for which in Eze 1:24 המלּה קול (the voice of noise), and by מחנה קול ( Eze 1:24) the noise of a host is denoted.…”
