How to say "lion (literary)" in Arabic

Both languages tucked away a poetic word for lion that everyday speech mostly replaced: layth is Hebrew layish (לַיִשׁ, the lion of Isaiah and Proverbs, and the name of a Biblical town) — ث lines up with ש here, the regular correspondence behind thalāth/shalosh (three); the ת' used elsewhere to transliterate ث phonetically is a different thing from this cognate-letter match.
