STRONGS NT 4739: στήκω

στήκω; (an inferior Greek word, derived from ἕστηκα, perfect of ἵστημι; see Buttmann, 48 (41); (Winers Grammar, 24, 26 (25); WH. Appendix, p. 169; Veitch, under the word (ἑστήκω; Mullach, under the word στέκω (p. 299))); to stand: Mark ( T Tr WH); Mark 11:25 ((cf. ὅταν c. β.)); John 1:26 L marginal reading T Tr text WH; (Revelation 12:4 WH (but see below)); with an emphasis, to stand firm; tropically, to persist, persevere (A. V. stand fast): absolutely to persevere in godliness and rectitude, 2 Thessalonians 2:15; ἐν κυρίῳ, in one's fellowship with the Lord, Philippians 4:1; 1 Thessalonians 3:8 ((cf. ἐάν, I. 2 b.)); ἐν τῇ πίστει, 1 Corinthians 16:13; ἐν ἑνί πνεύματι, Philippians 1:27; to keep one's standing (opposed to ζυγῷ ἐνέχομαι), τῇ ἐλευθερία, maintain your allegiance to freedom (cf. Winers Grammar, § 31, 1 k.; Buttmann, § 133, 12; but L T Tr WH take στήκετε here absolutely; cf. Lightfoot ad loc.), Galatians 5:1; to stand erect, tropically, not to sin (opposed to πίπτειν equivalent to to sin), τῷ κυρίῳ, dative commodi (Winer's Grammar, as above), Romans 14:4. (In John 8:44 (ἐν τῇ ἀλήθεια οὐκ ἔστηκεν) WH read the imperfect ἔστηκεν (where others adopt ἕστηκεν from ἵστημι), owing to the preceding οὐκ (T WH after manuscripts א B* D L etc.); see Westcott's Commentary on John, the passage cited 'Additional Note'; WH, Introduction, § 407. But such an imperfect is nowhere else found (yet cf. Revelation 12:4 WH), and respecting confusion in the ancient use of the breathings, and the interchange of οὐκ and ὀχ, see οὐ at the beginning and references there, especially Tdf. Proleg., p. 90; moreover, the familiar perfect (present) of ἵστημι thoroughly suits the context; see ἵστημι, II. 2 d.) ((The Sept., Exodus 14:13, Alex., Complutensian; 1 Kings 8:11); Alex.; Aphr. probl. 1, 49 vat.; ecclesiastical writings.)
