For the term in Matthew 4:9 that is translated as «fall down» or «kneel down» in English, Fuyug uses an idiomatic expression that says “kneel at my roots” (as of a tree).
In the Kölsch translation (publ. 2017) it is translated as «lie on your nose.» (Source: Jost Zetzsche)
See also knee / kneel and kneel / fall down / worship.
