'Stiff' in the Bible

for I know thy rebellion, and thy stiff neck. Lo, while I am yet alive with you this day, ye have been rebellious against Jehovah; and how much more after my death!

Lift not up your horn on high; speak not arrogantly with a stiff neck.

But the house of Israel will not hearken unto thee, for none of them will hearken unto me. For all the house of Israel are hard of forehead and stiff of heart.
