'Earthenware' in the Bible

Thus said Yahweh, "Go and buy a potter's earthenware jar, and [take] some of the elders of the people, and some of the leaders of the priests,

'Thus says Yahweh of hosts, the God of Israel, "Take these deeds, this deed of the purchase, the sealed one, and this opened deed, and you must put them in an {earthenware jar} so that they may be kept preserved many days."

But we have this treasure in earthenware jars, in order that the extraordinary degree of the power may be from God and not from us.

Now in a great house [there] are not only gold and silver vessels, but also wooden and earthenware [ones], some of which [are] for honorable use, and some of which [are] for ordinary use.
