Buttmann, as above, and Meyer at the passage). ἐκ with the genitive of place: ἐκ τοῦ ἱεροῦ, draw their support from the temple, i. e. from the sacrifices and offerings, 1 Corinthians 9:13 (but T Tr WH read τά ἐκ τοῦ ἱεροῦ); also ἐκ θυσιαστηρίου, i. e. from the things laid on the altar, Hebrews 13:10 (Winer's Grammar, 366 (344)). by a Hebraism (מִן אָכַל), ἀπό τίνος (cf. Winer's Grammar, 199 (187)): Matthew 15:27; Mark 7:28. Metaphorically, to devour, consume: τινα, Hebrews 10:27; τί, Revelation 17:16; of rust, James 5:3. (Compare: κατεσθίω, συνεσθίω.)

STRONGS NT 2068: ἔσθωἔσθω, equivalent to ἐσθίω, a poetic form in use from Homer down, very rare in prose writings; from it are extant in the N. T. the participle ἔσθων in Mark 1:6 T Tr WH; (Luke 10:7 L T Tr WH); Luke 7:33 L Tr WH, (also 34 WH); the present subjunctive 2 person plural ἔσθητε in Luke 22:30 L T Tr WH; (cf. κατεσθίω). It occurs several times in the Sept., as Leviticus 17:10; Judges 14:9 (Alex.); Isaiah 9:20; Sir. 20:16; ἔσθετε, Leviticus 19:26. Cf. (Tdf. Proleg., p. 81); Buttmann, 58 (51).
