Matthew Poole and continuators on Ezekiel 1:16

16 The appearance of the wheels, and their work was like unto the colour of a Beryl : and they four had one likeness , and their appearance and their work was as it were a wheel in the middle of a wheel.

The form in which these wheels were seen.

All that was wrought, whether engraved or otherwise was of one colour,

Heb. Tharshish, a Sea-green, some say this colour here was of a Carbuncle, or Chrysolite, or Hyacinth, but tis better rendred a Sea-green colour, which if it note the instability, and changeableness of sublunary affairs, and of the outward concerns of the Church, it may note also the inherent vigor, and beauty of the Church, and the frame of earthly things, when they are in a calm course not disturbed first with sin, and then with punishment of sin.

By this it appears what was the number of the wheeles.

Exactly of the same make for dimensions, colour, frame, and motion, so that who sees and knowes one, sees and knows all, hereby noting the Harmony and likeness which is in Gods works, which are all framed, managed and governed by the same Wisdom, and consequently the same uncertainty in all things under the Sun.

'Tis somewhat difficult to unfold this. It is probable the Wheeles were framed so as to be an exact Sphere or Globe, which is easily rowled to any side or quarter, since it toucheth the Earth or Basis on which it stands in a point, and is exactly orbicular, it is fitter we note. 1. The unsearchableness of Divine methods. 2. The curious frame of them. 3. The connexion of one part with other. 4. The seeming interfering and real harmony, what would seem to hinder shall further Gods work. 5. How easily God can change affairs and move for or against a people.
