Ezekiel 1:7

And their feet [were] straight feet; and the sole of their feet [was] like the sole of a calf's foot: and they sparkled like the colour of burnished brass.

Ver. 7. And their feet were straight feet.] Importing their right progress in executing God's will. We must also "make straight or even paths for our feet, lest that which is lame be turned out of the way." Heb 12:13 See Ezekiel 1:9 .

And the sole of their feet was like the sole of a calf's foot] Round, and therefore easily turned. Hoc ad agilitatem et varietatem cursus spectat. The angels, because they see every way, so they are apt to go every way, and this with the greatest facility that can be.

And they sparkled.] So swiftly they went, that their feet seemed to sparkle or strike fire.

Like the colour of burnished brass.] Burnished, not blemished; polished, not polluted.
