Hosea 13:3. “Therefore they shall be as the morning cloud, and as the early dew that passeth away, as the chaff that is driven with the whirlwind out of the floor, and as the smoke out of the chimney.”

Things that are temporary: Clouds, dew, chaff, smoke.
We lived in Portland, Oregon when I was between the ages of 10 and 15. The summers were so beautiful! There would be morning clouds, even sometimes a little rain, but as the sun climbed, the clouds and the morning dew were burned away. Temporary.
Chaff is the useless dust from the grain that is threshed at harvest time. It is tossed into the air, and is blown away. It is light, without substance. Temporary.
Smoke from a chimney is the residue of the fire in the hearth or the oven, and is without substance. It blows away. Temporary.
So will be the safety and prosperity of God’s people, who have turned to idols, and have left God. All the good they hope for will disappear in the heat and the wind, because their idols are without substance.
The only permanent and dependable safety and rest lies in obedience to God. There, one can find substance, permanence, and peace.
