Note 75 — XXI
Reading edition
The T.R. has ἐνδείξασθε here, and so Westcott and Hort read in text, with א, C, D**, etc. Most editors read with B, D*, E, F, G, etc., ἐνδεικνύμενοι. The imperative certainly seems to be a change made to facilitate the construction. Reading the participle, we must supply ἐνδείξεσθε, and put a comma after ἐνδεικνύμενοι: "in showing it to them, [you will show it] before the Churches." This is the same kind of ellipsis as in ver. 23.
