'Touching' in the Bible

{their wings were touching one another}; {each of them went straight forward}, {without turning right or left}.

So [were] their faces; their wings [were] spread out {upward}; each [had] two touching one another and two covering their bodies.

And [it was] the sound of the wings of the living creatures touching lightly {one against the other}, and the sound of the wheels beside them and [the] sound of a great earthquake.
