AN 5.151“pañcahi, bhikkhave, dhammehi samannāgato suṇanto saddhammaṃ bhabbo niyāmaṃ okkamituṃ kusalesu dhammesu sammattaṃ. katamehi pañcahi? na kathaṃ paribhoti, na kathikaṃ paribhoti, na attānaṃ paribhoti, avikkhittacitto dhammaṃ suṇāti, ekaggacitto yoniso ca manasi karoti.
Bhikkhus, endowed with five things by listening to the good Teaching it is possible to enter the righteous way in wholesome states. What five? Not enjoying talking, not enjoying boasting, not enjoying life, listening to the Teaching with an undisturbed mind, and thinking wisely with the mind concentrated.
My opinion is ekaggacitto here means 'single minded'; to be single minded when engaging wise reflection. I am not sure 'concentration', in the sense of samadhi, is an appropriate rendering. However, in respect to jhana, ekaggacitto is single minded in respect to concentration (samadhi).
