“Have they no knowledge?
Those evildoers
Who eat up my people
As they eat bread.
Why do they not call upon Yahweh?”
Once again this is exactly like Psalm 14. The evildoers are stupid. They have no knowledge. They eat up Yahweh’s people. This metaphor seems to indicate what the evildoers were trying to do to Yahweh’s people. Why are they not calling on Yahweh? Here the term used is Yahweh and not merely God.
