STRONGS NT 2823: κλίβανος

κλίβανος, κλιβανου, ὁ (for κρίβανος, more common in earlier (yet κλίβανος in Herodotus 2, 92 (cf. Athen. 3, p. 110 c.)) and Attic Greek; see Lob. ad Phryn., p. 179; Passow, under the word κρίβανος; (Winer's Grammar, 22));

1. a clibanus, an earthen vessel for baking bread (Hebrew תַּנּוּר, Exodus 8:3 ( in Hebrew); Leviticus 2:4; Leviticus 26:26; Hosea 7:4). It was broader at the bottom than above at the orifice, and when sufficiently heated by a fire kindled within, the dough was baked by being spread upon the outside (but according to others, the dough was placed inside and the fire or coals outside, the vessel being often perforated with small holes that the heat might the better penetrate; cf. Rich, Dictionary of Greek and Roman Antiquity, under the wordclibanus; see Schol. on Aristophanes Acharn. 86 (iv. 2, p. 339, 20f Dindorf)).

2. equivalent to ἰπνός, a furnace, an oven: so Matthew 6:30; Luke 12:28.
