I am stuck and the word “rubble” comes to my mind.

It does not take me long to find it in Nehemiah 4:10, where it says,

“Meanwhile, the people in Judah said, ‘The strength of the laborers is giving out, and there is so much rubble that we cannot rebuild the wall.'”

I have not even done away with the rubble, but I have decided to do so and I am unstuck.

You should try it, it works!
