[1] Masculine accusative singular or neuter nominative/accusative plural of the adjective e(ptaplasi/wn, instead of the more common e(ptapla/sios. It must be quoted from somewhere, very probably Psalm 78.12 LXX (cf. under kappa 27); cf. Theodoret on the passage.
[2] See again under kappa 27; and generally on the non-numerical properties of seven (and its multiples) D. Whitehead, Hypereides: the forensic speeches (Oxford 2000) 422.
