κατηχέω, 
κατήχω: 1 aorist 
κατήχησα; passive, present 
κατηχοῦμαι; perfect 
κατήχημαι; 1 aorist 
κατηχήθην; nowhere met with in the O. T.; very rare in secular authors; 
1. properly, 
to sound toward, sound down upon, resound: 
ἁρμονία κατηχει τῆς θαλαττης, 
Philostr., p. 791 (icon. 1, 19); to charm with resounding sound, to fascinate, 
τινα μύθοις, 
Lucian, Jup. trag. 39. 
2. to teach orally, to instruct: 
Lucian, asin. § 48; Philopatr. 17. In the N. T. only used by Luke and Paul: 
τινα, 
1 Corinthians 14:19; passive 
ἐκ τοῦ νόμου, by bearing the law, accustomed to be publicly read in the synagogues, 
Romans 2:18; with the accusative of the thing, 
αὐτός σε πολλά κατηχήσω τῶν ἀγνωυμενων, 
Josephus, de vita sua §65 at the end; with accusative of a thing and of a person, 
τοῦ ἀληθοῦς λόγου βραχέα κατηχησας με, Clement. hom. 1, 13; passive with the accusative of the thing: 
τήν ὁδόν τοῦ κυρίου, 
Acts 18:25; 
τόν λόγον, 
Galatians 6:6; hence, some ((see Meyer, in the place cited)) resolve 
Luke 1:4 thus: 
περί τῶν λόγων, 
οὕς κατηχήθης (see below). 
3. to inform by word of mouth; passive 
to be orally informed: followed by

ὧν, 
κατήχηνται περί σου i. e.

ἅ κτλ., 
Acts 21:24 (
κατηχηθεις περί τῶν συμβεβηκότων (pseudo-) 
Plutarch, de fluviis (7, 2); 8, 1; 7, 1). To this construction the majority refer 
Luke 1:4, construing it thus: 
τήν ἀσφάλειαν τῶν λόγων, 
περί ὧν κατηχήθης (
Winers Grammar, 165 (156); 
Buttmann, § 143, 7; (see above)). Cf. Gilbert, Dissertatio de christianae catecheseos historia (
Lipsius 1836) Part i., p. 1ff; Zezschwitz, System der christl. Katechetik (Leipz. 1863) i., p. 17ff; (and for ecclesiastical usage, Suicer, Thesaurus 2:69ff; 
Sophocles' Lexicon, under the word).
