6.108 · Artifacts · Furniture
bed a piece of furniture used for sleeping It is not necessary to understand LUK 11:7 to mean that the children were in the same bed with the man, but it is, of course, possible that the reference here is to a relatively humble house in which all the members of the family would sleep on a single raised platform. See also 10.37.
23.62 · Physiological Processes and States · Sexual Relations
sexual activity, sexual life, marriage relations (a figurative extension of meaning of κοίτη[a] ‘bed,’ 6.108) to have sexual relations In some languages one may speak of ‘sexual life’ as ‘the way one lives with one’s wife’ or ‘how one treats one’s wife.’
88.273 · Moral and Ethical Qualities and Related Behavior · Sexual Misbehavior
sexual immorality, lasciviousness to engage in immoral sexual excess
23.50 · Physiological Processes and States · Birth, Procreation
Collocation: κοίτην ἔχω
pregnant, to be pregnant (an idiom, literally: to have bed, though in combination with ἔχω, κοίτη early acquired the metonymic meaning of sexual relations) to be in a state of pregnancy This expression contrasts with the meaning of συλλαμβάνω[b], 23.49, in that it seems to focus more upon the state of pregnancy rather than the event of conception.
1 κοίτη[c] sexual immorality is a peripheral extension of meaning of κοίτη[b] sexual relations (see 23.62). This is due to a process of semantic narrowing.

Moulton & Milligan — Vocabulary of the Greek NT
κοίτη in the sense of “bed’’ occurs in the Serapeum dream P Par 511} (B.c. 160) (= Selections, p. 19) μεταβέβλ[ηκα] τὴν κοίτην μου, ‘I have changed my bed”’: ef. also the Christian letter written by a sick woman, P Oxy VIII. 1161}°(iv/a.p.) -- πάνυ μὴ δυναμένη ἀναστῆναι ἐκ τῆς κοίτης μου, ‘quite unable to rise from my bed.” The word seems to have the general meaning of “‘resting-place” in P Lips I. 1185 (a.p. 160-1), where ground is set aside εἰς βρῶσιν προβάτων καὶ κοίτην. In this way κοίτη is frequently used of a ‘‘ parcel” of land (cf. σφραγίς) as in P Ryl 11. 168% (A.D. 120) κοίτην ἣν ἐγεώργει Φιβίων, ““4 parcel cultivated by Phibion,’’ P Amh II. 88® (a.p. 128) ἐν δυσὶ κοίταις ἀρούρας ἑπτά, ““seven arourae in two parcels,” etc. The derived meaning “box,” ““chest,” is seen in P Petr II. 4 (6)? (B.c. 255-4) διὰ τὸ μὴ εἶναι ἄρτους ἐν τῇ κοίτῃ, P Tebt I. 180 (B.C. 92 or 59) εἰσὶν οἱ δεδωκ(ότες) χαλκὸν εἰς τὴν κοίτην Εἰὑρήμονος. For the verb κοιτάζω, which is found in the LXX, cf. P Oxy XII. 1465° (i/B.c.) τοὺς ἄλλους τοὺς ἐκεῖ κοιταζο[μέ]vous, ‘‘the others who sleep there” (Edd.), for the subst. κοιτασμός cf. P Tebt II. 423! (early iii/a.p.) ἐὰν οὖν μὴ ἧς λαβὼν τὰ πρόβατα πρὸς κοιτασμός (/.-dv), ‘so if you have not received the sheep for folding” (Edd.), for ἀπόκοιτος cf, 24, 384° (A.D. 10) οὐ γεινόμενος (/.-ov) ἀπόκοιτον οὐδ᾽ ἀφ[ήμερον ἀπ]ὸ τῆς [ΤΤασώνιος] οἰκίας, ‘he shall not sleep away or absent himself by day from Pasonis house ” (Edd,), and for ἐκκοιτεία see P Tebt II. 332° (s.v. καιρός). With the use of κοίτη for “‘sexual intercourse” in Rom 134 we may compare the verb ἀνδροκοιτέω in BGU IV. 1106% (B.c. 13), P Cairo Preis 3153 (A.D. 139-140).
