A very clean Thursday with a cute little theme. Well, I suppose I should say with an "epic" theme, because that's what MOSES's PARTING of the RED SEA has become, right? In addition, we have the PHARAOH of EGYPT, and the ISRAELI. Very nice, but don't you kind of miss the "-tes" at the end of that last one? And are EMIGRATED (20A: Left for good) and PESACH (25A: Feast of unleavened bread) bonus theme material? And hey, maybe even SADAT (27D: October War leader) and EBAN (33A: Nonmusical Abba).
The rest of the fill is remarkably clean, and includes such lovely things as BEERPONG (10D: Party game), PTOMAINE (37D: Product of organic decay) (!), GUARANTOR (50A: Co-signer, say), and HEDONIST (15A: One who's just out for a good time). There's some capital symmetry with HONOLULU (28A: Southernmost U.S. capital) and STTHOMAS (44A: Home of Charlotte Amalie), and really, not much to complain about at all. Maybe AVAS, OSTE, or IDAS… but, well… that's not much.
