Oven in Fausset's Bible Dictionary
            tanur. Fixed or portable. The fixed ovens were inside towns. 
The portable ovens consisted of a large clay jar, three feet 
high, widening toward the bottom, with a hole to extract the 
ashes. Sometimes there was an erection of clay in the form 
of a jar, built on the house floor. Every house had one 
(Exodus viii. 3 ); only in a famine (lid one suffice for 
several faro-flies (Leviticus xxvi. 26). Tile heating fuel 
was dry grass and twigs (Blurt. vt. 30: "grass, which to-day 
is, to-morrow is cast into the oven"). The loaves were 
placed inside, and thin cakes outside of it. 
 Image of consuming vengeance (Malachi 4:1). Psalm 
21:9; "Thou shalt make them as a fiery oven in the time of 
Thine anger... burning with Thy hot, wrath in the day of the 
Lord." Hosea 7:4, 7: "they are all adulterers, as an oven 
heated by (burning from) the baker," i.e. the fire burns of 
itself, even after tlle baker has ceased to feed it with 
fuel. "Who teaseth from raising (rather from heating it 
meeir) after he hath kneaded the dough until it be 
leavened:" he omits to feed it only during the short time of 
the fermentation of the bread. So their lusts were on fire 
even in the short respite that Satan gives, till his leaven 
has worked. 2 Peter 2:14, "cannot cease from sin."
