The Hebrew in Psalm 23:2 that is often translated as «still waters» in English is translated as “water at the mouth of a well” in Dan since «the imagery of ‘still water’ is seen as something negative, water that is dirty since it isn’t moving.» (Source: Don Slager)

In the Contemporary Chichewa translation (2002/2016) it is translated as «clean/good drinking water.» (Source: Mawu a Mulungu mu Chichewa Chalero Back Translation)
