How different it is with the wicked ones! They may appear to prosper for a time, but they have no abiding security. The psalmist continues: “The wicked are not like that, but are like the chaff that the wind drives away.

Ps. 1:4-6.

Accordingly, the wicked ones have no more security than does chaff during the winnowing process. The chaff is blown away while the heavier kernels of grain drop to the ground. Similarly, the righteous remain but the wicked are blown away like worthless chaff.
