1 Kings 18:32

a trench The LXX. has θάλασσαν = a sea, which is interesting in connexion with the name given to the great cistern which Solomon caused to be made for the temple-services. Cf. 1 Kings 7:23 above.

as great as would contain two measures of seed The LXX. omits these words, which are not quite easy of explanation. The measure mentioned is a seah, which is the third part of an ephah. But whether the dimension applies to each side of the altar, so that on each of the four sides there would be a ditch of this capacity, or whether this was the capacity of the whole surrounding trench is not evident. It was clearly intended to catch the water that was poured over the sacrifice.
