'Doing' in the Bible

Then the Lord said to Joshua, Get up; what are you doing with your face to the earth?

And the Canaanites who were living in Gezer were not forced out; but the Canaanites have been living among Ephraim, to this day, as servants, doing forced work.

You have now been with your brothers for a long time; till this day you have been doing the orders of the Lord your God.
