Same entry in ps.-Zonaras and, according to Adler, the Ambrosian Lexicon. The headword verb e)kkake/w appears in New Testament manuscripts (of e.g. Luke 18.1) as a variant reading for e)gkake/w; see LSJ s.v.
[1] This gloss does not seem to relate to the headword (unless it is a sheer misunderstanding of it). Dindorf suggested emending to a)pokakw=, "I sink under a weight of misery." Bernhardy, comparing epsilon 1602, proposed a)pagoreu/w, a)pokakw=.
[2] Here Alberti proposed adding kai\ mh\ e)kkakw= "...and not lose heart." (But the quotation, if such it is, is unidentifiable.)
