Verse 4: “Not so the wicked! They are like chaff that the wind blows away.”
I like food analogies. Grains would be tossed into the air after being harvested, so that the useless, inedible chaff would blow away, separating it from the grain.
Someday, I would like to grow my own grain, and then I will have to read this passage, so that I get the full image of the chaff being blown away.
