The standard liquid measure — the same volume as the dry ephah.
Volume (liquid)
20–24 L (5.28–6.34 gal).
Defined as 1 ephah.
Inherits the disagreement over the ephah.
The bath is the liquid twin of the ephah, and Ezekiel says so explicitly while insisting on honest measures. It is the unit the temple's bronze Sea is given in, and the one the dishonest steward's debtors owe their oil in.
The bath is the liquid twin of the ephah: the same volume, measuring oil and wine instead of grain. A hin is a sixth of it, the measure the drink offerings are given in, and a log a twelfth of a hin. Each jar holds its measure at the middle of the range. The Sea’s shape is only sketched: the text gives its breadth and height, not its profile.
