God puts his bow in the clouds

All I know was that putting His bow in the clouds was part of His promise to Abraham that He would never again send a worldwide flood. But He will one day destroy the Earth by fire.
An arc is just an arc.
A bow on the other hand can be something that goes on and on and on… with a part of it being in a “bow” shape.

The rainbow symbol is something that signifies a promise that will go on and on and on…

And as far as being connected with Jesus coming back in the clouds?
I believe it is. Everything of God is connected in some way. :D
