Okay, one more, this is interesting:
Mic 3:7: "Then shall the Seers be ashamed, and the Soothsayers confounded: yea, they shall all cover their lips, for they have none answer of God."
see also Eze 24:17 & Lev 13:45
- covering of the lips/mouth as a sign of one's sickness (leprosy)
- and a sign that GOD DOES NOT ANSWER anymore!
