(Βηθζαθά) ἡ (perhaps from Chaldean זַיְתָא בֵּית, house of olives; not, as some suppose, חֲדַתָּא בֵּית, house of newness, German Neuhaus, since it cannot be shown that the Hebrew letter chet ח is ever represented by the Greek zeta ζ'), Bethzatha: T (WH text) after manuscripts א L D and other authorities (no doubt a corrupt reading, yet approved by Keim, ii., p. 177 (see also WH s Appendix, ad loc.)), for Βηθεσδά, which see (Cf.
