When they stood, these stood; and when they were lifted up, these lifted up themselves also: for the spirit of the living creature was in them.
When they stood, these stood; and when they were lifted up, these lifted up themselves also: for the spirit of the living creature was in them - (Ezekiel 1:12; Ezekiel 1:20-21; "When those went, these went; and when those stood, these stood; and when those were lifted up from the earth, the wheels were lifted up over against them: for the spirit of the living creature was in the wheels").
Stood. God never stands still (John 5:17), therefore neither do the angels; but to human perceptions He seems to do so.
