G1573–ἐκκακέω–ekkakeō

He also spoke a parable to them that they must always pray, and not give up,

ἐγκακεῖν egkakein “to lose heart”

Therefore seeing we have this ministry, even as we obtained mercy, we don't faint.

ἐγκακοῦμεν, egkakoumen “we lose heart,”

Therefore we don't faint, but though our outward man is decaying, yet our inward man is renewed day by day.

ἐγκακοῦμεν· egkakoumen “we lose heart;”

Let us not be weary in doing good, for we will reap in due season, if we don't give up.

ἐγκακῶμεν· egkakōmen “we may grow weary;”

Therefore I ask that you may not lose heart at my troubles for you, which are your glory.

ἐγκακεῖν egkakein “to lose heart”

But you, brothers, don't be weary in doing well.

ἐγκακήσητε egkakēsēte “may grow weary”
