A personal name appearing in Jeremiah's account of the Rechabites, that faithful clan who refused wine in obedience to their ancestor Jonadab. Habazziniah was the grandfather of Jaazaniah, whom Jeremiah brought to the temple to test the Rechabites' loyalty. The name may derive from a root meaning 'to hide' or 'to treasure,' though this remains uncertain. He stands in the genealogy of those whose covenant faithfulness shamed unfaithful Judah.
