Psalms 68:17

The chariots of God [are] twenty thousand, [even] thousands of angels: the Lord [is] among them, [as in] Sinai, in the holy [place].

Ver. 17. The chariots of God are twenty thousand] Heb. The chariot, to note the joint service of all the angels, who are here called Shinan, of their changeableness now taken away by Christ, say some; of their pre-excelleney above other creatures, say others, as being second or next unto God, the chief princes, the nobles of that court, as Daniel 10:13, Michael one of the chief princes. The Seventy render it ευθυμουντων, the cheerful ones such as are in joy and tranquillity, freely serving God in all his wars, carrying the elect, and marching about them.

The Lord is among them, as in Sinai] i.e. The angels make Sion as dreadful to all her enemies as those angels made Sinai at the delivery of the Law. See Hebrews 12:22 .

In the holy place] Holy for the time while God appeared there, so 2 Peter 1:18, Tabor is called the holy mount.
