'Stones' in the Bible

And do not think to say within yourselves, We have Abraham for our father; for I say unto you, that God is able of these stones to raise up children to Abraham.

And the tempter coming up to him said, If thou be Son of God, speak, that these stones may become loaves of bread.

Jerusalem, Jerusalem, the city that kills the prophets and stones those that are sent unto her, how often would I have gathered thy children as a hen gathers her chickens under her wings, and ye would not!
