Lexicon :: Strong's G2531 - kathōs

καθώς (i. e. καθ' ὡς), a particle found occasionally in secular authors from Aristotle down for the Attic καθά and καθό, but emphatically censured by Phryn. and the Atticists; cf. Sturz, De dial. Maced. etc., p. 74ff; Lob. ad Phryn., p. 425f; (Winer's Grammar, 26 (25));
1. according as, just as, even as: in the first member of a comparison, Luke 6:31; 1 John 2:27; followed by οὕτως in the second member (cf. Winer's Grammar, § 53, 5), Luke 11:30; Luke 17:26; John 3:14; 2 Corinthians 1:5; 2 Corinthians 10:7; Colossians 3:13; 1 John 2:6; followed by καί also, John 15:9; John 17:18; John 20:21; 1 John 2:18; 1 John 4:17; 1 Corinthians 15:49; it is annexed to preceding words after the demonstrative οὕτως, Luke 24:24; with οὕτως unexpressed, Matthew 21:6; Matthew 28:6; Mark 16:7; Luke 1:2, 55, 70; Luke 11:1; John 1:23; John 5:23; Acts 10:47 (here L T Tr WH ὡς); Acts 15:8; Romans 1:13; Romans 15:7; 1 Corinthians 8:2; 1 Corinthians 10:6; 2 Corinthians 1:14; 2 Corinthians 9:3; 2 Corinthians 11:12; Ephesians 4:17, and often; καθώς διδάσκω, agreeably to my method of teaching, 1 Corinthians 4:17; καθώς γέγραπται, Matthew 26:24; Mark 9:13; Acts 7:42; Acts 15:15; Romans 1:17, and often in Paul; the apodosis lacking, and to be gathered from the context: καθώς παρεκάλεσα σε... ἐν πίστει, namely, οὕτω καί νῦν παρακαλῶ, 1 Timothy 1:3, cf. Winers Grammar, 570 (530); (Buttmann, 386 (331)); ἤρξατο αἰτεῖσθαι (namely, οὕτω ποιεῖν αὐτοῖς), καθώς κτλ.. Mark 15:8 (Buttmann, § 151, 23 b.; cf. Winer's Grammar, 584 (543f)); in comparison by contrary we find the negligent use: ἀγαπῶμεν ἀλληλου, οὐ καθώς Κάϊν κτλ., 1 John 3:11f, cf. DeWette at the passage and Winer's Grammar, 623 (579); οὗτος ἐστιν ὁ ἄρτος... οὐ καθώς etc., not such as they ate etc., John 6:58. with the verb εἰμί, equivalent to Latin qualis, such as, 1 John 3:2; in a parenthesis, 1 Thessalonians 2:13 (as it is in truth).
2. according as i. e. in proportion as, in the degree that: Mark 4:33; Acts 7:17 (cf. Meyer at the passage); Acts 11:29; 1 Corinthians 12:11, 18; 1 Peter 4:10.
3. since, seeing that, agreeably to the fact that (cf. Winer's Grammar, § 53, 8; 448 (417)): John 17:2; Romans 1:28 (yet here others regard καθώς as corresponsive rather than causal or explanatory); 1 Corinthians 1:6; 1 Corinthians 5:7; Ephesians 1:4; Philippians 1:7.
4. it is put for the simple ὡς,
a. after verbs of speaking, in indirect discourse, Acts 15:14; it serves to add an epexegesis, 3 John 1:3 (to σου τῇ ἀλήθεια).
b. of time, when, after that (cf. Latin ut): 2 Macc. 1:31; (Nehemiah 5:6); here many bring in Acts 7:17; but see 2 above.
