Ezekiel 1 verse 9

Thus were their faces: and their wings were stretched upward; two wings of every one were joined one to another, and two covered their bodies.

And the wings of the cherubims were twenty cubits long: one wing of the one cherub was five cubits, reaching to the wall of the house: and the other wing was likewise five cubits, reaching to the wing of the other cherub. And one wing of the other cherub was five cubits, reaching to the wall of the house: and the other wing was five cubits also, joining to the wing of the other cherub.

And the likeness of their faces was the same faces which I saw by the river of Chebar, their appearances and themselves: they went every one straight forward.

Let thine eyes look right on, and let thine eyelids look straight before thee. Ponder the path of thy feet, and let all thy ways be established. Turn not to the right hand nor to the left: remove thy foot from evil.

And it came to pass, when the time was come that he should be received up, he stedfastly set his face to go to Jerusalem,

And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God.
