An impure quartz rock, usually gray, brown, or black, abundant in Palestine. It fractures on conchoidal lines and holds an extremely sharp edge, either smooth or serrated. It was used for a variety of tools, such as awls, axes, knives, picks, scrapers, sickles, and weapons (arrowheads and spear points). Knives used for circumcision were made of flint (Exod 4:25
; Josh 5:2
; Josh 5:3
). Flint serves as a metaphor for sharp-cutting destructive power (Isa 5:28
) and stubborn faithfulness (Isa 50:7
) and is a dubious source of water (Ps 114:8
; Deut 8:15
). It can be manipulated by humans (Job 28:9
), but is a most unlikely source of any nourishment (Deut 32:13

2At that time the Lord said to Joshua, “Make flint knives and circumcise the Israelites a second time.”
3So Joshua made flint knives, and circumcised the Israelites at Gibeath-haaraloth.

all their bows bent,
their horses' hoofs seem like flint,
and their wheels like the whirlwind.
7The Lord GOD helps me;
therefore I have not been disgraced;
therefore I have set my face like flint,
and I know that I shall not be put to shame;
8who turns the rock into a pool of water,
the flint into a spring of water.
15who led you through the great and terrible wilderness, an arid wasteland with poisonous snakes and scorpions. He made water flow for you from flint rock,
9“They put their hand to the flinty rock,
and overturn mountains by the roots.
13He set him atop the heights of the land,
and fed him with produce of the field;
he nursed him with honey from the crags,
with oil from flinty rock;
