1 The various terms noted in 35.1 (ἀντιλαμβάνω[a], ἐπιλαμβάνομαι[d], ὑπολαμβάνω[c], συμβάλλω[e], παρίστημι[l], ἀντέχω[c], ἐπαρκέω[a], βοηθέω, βοήθεια[a]) with a generic meaning of ‘help’ no doubt possess certain contrastive features of meaning, at least of a connotative type, but there is no specific evidence of this in NT usage.
