Moulton & Milligan — Vocabulary of the Greek NT
κοίτη [page 351]
κοίτη in the sense of bed occurs in the Serapeum dream P Par 51 .11 (B.C. 160) (= Selections , p. 19) μεταβέβλ [ηκα ] τὴν κοίτην μου , I have changed my bed : cf. also the Christian letter written by a sick woman, P Oxy VIII. 1161 .10 (iv/A.D.) 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. 118 .15 (A.D. 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 II. 168 .9 (A.D. 120) κοίτην ἣν ἐγεώργει Φιβίων , a parcel cultivated by Phibion, P Amh II. 88 .9 (A.D. 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) .10 (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 Εὑρήμονος . For the verb κοιτάζω , which is found in the LXX, cf. P Oxy XII. 1465 .9 (i/B.C.) τοὺς ἄλλους τοὺς ἐκε̣ῖ κο̣ιταζο [μέ ]νους , the others who sleep there (Edd.), for the subst. κοιτασμός cf. P Tebt II. 423 .19 (early iii/A.D.) ἐὰν οὖν μὴ ἦς λαβὼν τὰ πρόβατα πρὸς κοιτασμός ( l. όν ), so if you have not received the sheep for folding (Edd.), for ἀπόκοιτος cf. ib. 384 .6 (A.D. 10) οὐ γεινόμενος ( l. ον ) ἀπόκοιτον οὐδ᾽ ἀφ [ήμερον ἀπ ]ὸ τῆς [Πασώνιος ] οἰκίας , he shall not sleep away or absent himself by day from Pasonis house (Edd.), and for ἐκκοιτεία see P Tebt II. 332 .9 ( s.v. καιρός ). With the use κοίτη for sexual intercourse in Rom_13:13 we may compare the verb ἀνδροκοιτέω in BGU IV. 1106 .29 (B.C. 13), P Cairo Preis 31 .24 (A.D. 139 140).

Bed (conceived, sexual promiscuity) (2845) koite
Sexual promiscuity (2845) (koite) literally refers to a place for lying down and rest and thus refers to a bed or bedroom. Koite was used also of the den of an animal or the nest of a bird as well as of a box or basket.
In certain contexts it was used to refer to the marriage bed and conveyed the same idea of our English phrase "going to bed" does today. Koite is also described illicit sexual promiscuity, as in this present verse.
Barclay writes that koite...
literally means a bed and has in it the meaning of the desire for the forbidden bed. This was the typical heathen sin. The word brings to mind the man who sets no value on fidelity and who takes his pleasure when and where he will. (Barclay, W: The Daily Study Bible Series, Rev. ed. Philadelphia: The Westminster Press)
Luke uses koite literally writing...
and from inside he shall answer and say, 'Do not bother me; the door has already been shut and my children and I are in bed; I cannot get up and give you anything.' (Luke 11:7)
Koite is used of the honored marriage bed, the writer of Hebrews exhorting the readers to...
"Let marriage be held in honor among all, and let the marriage bed (koite) be undefiled; for fornicators and adulterers God will judge." (Heb 13:4-note)
Earlier Paul used koite to describe legitimate conception...
And not only this, but there was Rebekah also, when she had conceived twins by one man, our father Isaac (Ro 9:10-note)
Comment: Here koite occurs in the expression koiten echousa, (literally = bed having) and is a euphemism for coitus, and, by expansion, conception and pregnancy.
Koite - 4x in NAS - Lk 11:7; Ro 9:10, Ro 13:13; Heb 13:4. NAS = bed, 2; conceived, 1; sexual promiscuity, 1.
Koite is found some 81 times in the Septuagint - LXX (Ge 49:4; Ex 10:23; 21:18; Lev 15:4, 5, 16, 17, 21, 23, 24, 26, 32; 18:20, 22, 23; 19:20; 20:13; 22:4; Nu 5:13, 20; 31:17-18, 35; Judges 21:11,12; 2Sa 4:5, 11; 11:2, 13; 13:5; 17:28; 1 Ki 1:47; 1 Chr 5:1; Est 4:17; Job 7:13; 33:15, 19; 36:28; 37:8; 38:40; Ps 4:4; 36:4; 41:3; 149:5; Pr 7:17; Song 3:1; Isaiah 11:8; 17:2; 56:10; 57:7; Jer 10:22; 50:6; Ezek 23:17; Dan 2:28, 29; 4:5, 8, 10, 13; 7:1, 2; Hos 7:14; Mic 2:1, 12)
