Lukas 8:15

8:15 But as for the seed that landed on good soil, these are the ones who, after hearing ¹  the word, cling to it ²  with an honest and good ³  heart, and bear fruit with steadfast endurance. ⁴ 

Lukas 21:19

21:19 By your endurance ⁵  you will gain ⁶  your lives. ⁷ 

[8:15]  ¹ tn The aorist participle ἀκούσαντες (akousante") has been taken temporally, reflecting action antecedent (prior to) that of the main verb.

[8:15]  ² sn There is a tenacity that is a part of spiritual fruitfulness.

[8:15]  ³ sn In an ancient context, the qualifier good described the ethical person who possessed integrity. Here it is integrity concerning God’s revelation through Jesus.

[8:15]  ⁴ sn Given the pressures noted in the previous soils, bearing fruit takes time (steadfast endurance), just as it does for the farmer. See Jas 1:2-4.

[21:19]  ⁵ sn By your endurance is a call to remain faithful, because trusting in Jesus is the means to life.

[21:19]  ⁶ tc Some important Greek witnesses plus the majority of mss (א D L W Ψ Ë¹ Ï) read the aorist imperative κτήσασθε (kthsasqe) here, though some mss (A B Θ Ë¹³ 33 pc lat sa) read the future indicative κτήσεσθε (kthsesqe). A decision is difficult because the evidence is so evenly balanced, but the aorist imperative is the harder reading and better explains the rise of the other. J. A. Fitzmyer assesses the translation options this way: “In English one has to use something similar [i.e., a future indicative], even if one follows the [aorist imperative]” (Luke [AB], 2:1341); in the same vein, although this translation follows the aorist imperative, because of English requirements it has been translated as though it were a future indicative.

[21:19]  ⁷ tn Grk “your souls,” but ψυχή (yuch) is frequently used of one’s physical life. In light of v. 16 that does not seem to be the case here. The entire phrase could be taken as an idiom meaning “you will save yourselves” (L&N 21.20), or (as in v. 18) this could refer to living ultimately in the presence of God.
