'Brittle' in the Bible

For my life nears its end in pain; my years draw to a close as I groan. My strength fails me because of my sin, and my bones become brittle.

When I kept silent, my bones became brittlefrom my groaning all day long.

When its branches get brittle, they break; women come and use them for kindling. For these people lack understanding, therefore the one who made them has no compassion on them; the one who formed them has no mercy on them.

and that the toes of the feet were partly iron and partly fired clay—part of the kingdom will be strong, and part will be brittle.
