Βάαλ (Rec. βαάλ), ὁ, ἡ, indecl. (Heb. בַּעַל, lord),
Baal: Rom.11:4 (LXX). The fem. art. here agrees with the usage of LXX, where, following a similar Hebrew practice (בֹּשֶׁת for בַּעַל), αἰσχύνη appears to have been substituted in reading for the written Βάαλ (cf. 3Ki.18:19), and to account for the frequently use of the fem. art. bef. Β. The usage, however, is not general, and in the passage cited in Ro (3Ki.19:18), LXX reads τῷ Β. †
