Ezekiel 1:14
And the living creatures ran and returned as the appearance of a flash of lightning.
And the living creatures ran,.... Did their work with great readiness and swiftness; so, especially in the latter day, ministers of the Gospel shall run to and fro, and knowledge shall be increased,
and returned; for though before it is said, "they turned not when they went", they kept straight on till they had done their work; but when they have done it, then they return, and give an account of it to him that has sent them: and their running and returning are said to be,
as the appearance of a flash of lightning; very sudden and swift.
