how, very, how great, how much, intense, severe a relatively high point on a scale involving exclamation In a number of languages an expression of high degree in an exclamation can only be reproduced as an expression of intensive degree in a non-exclamatory form. For example, the statement in MAT 6:23 ‘how great must the darkness be!’ must be rendered in a number of languages as ‘the darkness is very, very intense’ or ‘it is very, very dark there.’
In a number of languages the equivalent of ἡλίκον ἀγῶνα ἔχω in COL 2:1 would be ‘I struggle very much indeed.’

ἡλίκος. P Tebt I. 2778 (B.c. 113) (= Chrest. I. p. 390) καθόλου δ᾽ ἐνθυμηθεὶς ἡλίκην συμβάλλεται ἣ περὶ τὰ ὑποδεικνύμεν[α] προσοχὴι τοῖς πράγμασι ῥοπήν, “in general consider how great an impulse attention to the matters indicated gives to business ” (Edd.), Sy/Z 40514 (a.D. 145) ἐδήλζωσεν ὅσα κα]ὶ ἡλίκα οἰκοδομήματα προστίθησιν τῇ modfe. In the medical prescriptions P Oxy VIII. 1088* (early i/A.D.) κολλύρια moe. ἡλίκον Aiyim(tiov) κύαμον, ‘ ‘make pastilles of the size of an Egyptian bean” (Ed.), and 126. 11. 234% °° (ii/iii ἡλίκον [ὀ]ρόβῳ, “of the ἘΞ of a pea’ ’ (Edd.), the context suggests that, as in the case of the Lat. gwantus sometimes = guantulus, ἡλίκος from meaning ‘‘ how great’’ has come to mean also ‘‘how small”’ : cf. Jas 3°.
