Hosea 4:13

They sacrifice upon the tops of the mountains, and burn incense upon the hills.

Blustering sinners

That is the bold aspect, that is the public phase; instead of doing all these things, as Ezekiel would say, in a chamber of imagery far down, at which you get through a hole in the wall, they go up to high places, and invite the sun to look upon them; they kiss the calf in public. Some credit should be due to audacity, but there is another sin which cannot be done on the tops of the mountains, so the charge continues,--“under oaks and poplars and elms, because the shadow thereof is good.” Here is the secret aspect of rebellion. Do not believe that the blusterer lives only in public as fool and criminal; do not say, There is a fine frankness about this man anyhow; when he sins, he sins in high places; he goes upon the mountains, and stamps his foot upon the high hills, and the great hill throbs and vibrates under his sturdy step. That is not the whole man; he will seek the oak, the poplar, and the elm, because the shadow thereof is good. It is a broad shadow; it makes night in daytime; it casts such a shadow upon the earth which it covers that it amounts to practical darkness. So the blustering sinner is upon the mountain, trying to perpetrate some trick that shall deserve the commendation of being frank, and when he has achieved that commendation he will seek the shadow that is good, the shadow at daytime, the darkness underneath the noontide sun. How the Lord searches us, and tries our life, and puts His fingers through and through us, that nothing may be hidden from Him! He touches us at every point, and looks through us, and understands us altogether. (Joseph Parker, D. D.)
