'Sharp' in the Bible

And he took a broken bit of a pot, and, seated in the dust, was rubbing himself with the sharp edge of it.

I am broken by his wrath, and his hate has gone after me; he has made his teeth sharp against me: my haters are looking on me with cruel eyes;

The pillars of heaven are shaking, and are overcome by his sharp words.

Will you put sharp-pointed irons into his skin, or fish-spears into his head?

The sword may come near him but is not able to go through him; the spear, or the arrow, or the sharp-pointed iron.

Under him are sharp edges of broken pots: as if he was pulling a grain-crushing instrument over the wet earth.
