'Flinty' in the Bible

He led you through the great and terrible wilderness, with its fiery serpents and scorpions and thirsty ground where there was no water; it was He who brought water for you out of the flinty rock.

“He made him (Israel) ride on the high places of the earth,And he ate the produce of the field;And He made him suck honey from the rock,And [olive] oil from the flinty rock,

“Man puts his hand on [and tears apart] the flinty rock;He overturns the mountains at the base [looking for treasure].
