And behind the door, and behind the post thou best set up thy remembrance: for thou hast discovered thyself near me, and hast received an adulterer: thou hast enlarged thy bed, and made a covenant with them: thou hast loved their bed with open hand.

Behind the doors also and the posts hast thou set up thy remembrance: for apart from me, thou hast uncovered thyself, and art gone up; thou hast enlarged thy bed, and hast made agreement with them; thou lovedst their bed, thou sawest their nakedness.

And behind the doors and the posts hast thou set up thy memorial: for thou hast discovered thyself to another than me, and art gone up; thou hast enlarged thy bed, and made thee a covenant with them; thou lovedst their bed where thou sawest it.

And behind the door, and the post, Thou hast set up thy memorial, For from Me thou hast removed, and goest up, Thou hast enlarged thy couch, And dost covenant for thyself among them, Thou hast loved their couch, the station thou sawest,

Behind the doors also and the posts have you set up your remembrance: for you have discovered yourself to another than me, and are gone up; you have enlarged your bed, and made you a covenant with them; you loved their bed where you saw it.

And on the back of the doors and on the pillars you have put your sign: for you have been false to me with another; you have made your bed wide, and made an agreement with them; you had a desire for their bed where you saw it

And behind the doors and the posts Hast thou set up thy symbol; For thou hast uncovered, and art gone up from Me, Thou hast enlarged thy bed, And chosen thee of them Whose bed thou lovedst, Whose hand thou sawest.

And behind the door, and beyond the post, you have set up your memorial. For you uncovered yourself next to me, and you received an adulterer. You widened your bed, and you formed a pact with them. You loved their bed with an open hand.

Post ostium et postem posuisti memoriale tuum; discooperta es a me; ascendisti, dilatasti lectum tuum, fecisti cum iis foedus, dilexisti lectum eorum, loco quem vidisti.

Behind the door. He dwells largely on the crime of which we have already spoken, that the people may no longer flatter themselves in their inventions. It is probable that Isaiah alludes to the words of Moses, by which God commanded them to have the Law continually placed before them, to attach it to the posts of their houses, and to keep it written and wrapped around their arms and the fringes of their garments, that they might be constantly reminded of their duty. (Deuteronomy 6:9; 11:20) But the Jews, on the contrary, polluted the doors and posts of their houses by tokens of idolatry, and left no corner free or pure from such pollutions. Thus they came to forget everywhere God and the Law, and substituted in their room the excitements of their own lust. Thou hast enlarged thy bed. He again repeats what he formerly said, and returns to that clause, that the Jews most basely commit fornication with idols when they think that they are worshipping God; because they do not follow the rule of the word. It is the same as if a woman, having forsaken her husband, should prostitute herself in a brothel, and freely receive all that came, as if the bed had been a large plain, and capable of containing a vast multitude. For this reason he says that she was detected by him, because, having laid aside the modesty of the married state, she allowed herself to be dishonored and ravished by others; for God holds the place of a husband, to whom she ought to have been subject, but she sought new husbands, and broke the bond of marriage, he describes their aggravated guilt, by saying that the Jews of their own accord devoted themselves to idols, as if a base woman ran after a man with blind eagerness. Thou lovedst their bed in the place which thou sawest. By a different figure he accuses them of that hasty love, because, as if by a single glance, they were suddenly and eagerly hurried on to any place whatever. Yet he blames the rashness of men, who think that they are sagacious in worshipping God, and select places according to their own pleasure. But this sagacity is diabolical; for God commands us to keep our eyes fixed on himself and his word, so as to be closed against everything else.

Behind the doors - In every part of their habitations - behind the doors and posts and beams of their houses, they had erected the memorials of idolatrous worship.
Hast thou set up thy remembrance - That is, they had filled their houses with the images of tutelary gods, or with something dedicated to them. The Greeks and Romans had their Lares and Penates - their household or domestic gods - the images of which were in every family. The same was true of the apostate Hebrews. They had filled their houses with the memorials of idol-worship, and there was no part of their dwellings in which such memorials were not to be found. When a people forget God, the memorials of their apostasy will be found in every part of their habitations. The shrines of idol-gods may not be there; the beautiful images of the Greek and Roman mythology, or the clumsy devices of less refined pagans, may not be there; but the furniture, the style of living, will reveal from 'behind every door and the posts' of the house that God is forgotten, and that they are influenced by other principles than a regard to his name. The sofa, the carpet, the chandelier, the center-table, the instruments of music, the splendid mirror, may be of such workmanship as to show, as clearly as the image of a pagan god, that Yahweh is not honored in the dwelling, and that his law does not control the domestic arrangements. It may be added here that this custom of the Hebrews of placing the images of idols in their dwellings, was in direct violation of the law of Moses. They were expressly directed to write the laws of God on the posts of the house and on the gates Deuteronomy 6:9; Deuteronomy 11:20; and a curse was denounced against the man who made a graven or molten image and put it in a secret place Deuteronomy 27:15.
For thou hast discovered thyself - This language is taken from adulterous intercourse, and is designed to show the love which they had for idolatrous worship, and the extent of their unfaithfulness to God.
And made thee a covenant with them - Margin, 'Hewed it for thyself larger than theirs. The true sense is, that they had made an agreement with idolaters, or had entered into a covenant with them.
Thou lovedst their bed - Margin, 'Thou providest room.' Literally, 'Thou lovest their bed; thou hast provided a place for it.' The word יד yâd, rendered here 'where,' means literally a hand; then a side, a place (see the notes at Isaiah 56:5). The passage means, that they had delighted in the temples, altars, groves, and sacrifices of idolatry, and had provided a place for them in their own land.

Behind the doors also and the posts hast thou set up thy remembrance "Behind the door, and the door-posts, hast thou set up thy memorial" - That is, the image of their tutelary gods, or something dedicated to them; in direct opposition to the law of God, which commanded them to write upon the door-posts of their house, and upon their gates, the words of God's law; Deuteronomy 6:9; Deuteronomy 11:20. If they chose for them such a situation as more private, it was in defiance of a particular curse denounced in the law against the man who should make a graven or a molten image, and put it in a secret place; Deuteronomy 27:15. An ancient MS., with another, has אחר achar, without the conjunction ו vau, and.

Behind the (h) doors also and the door posts hast thou set up thy remembrance: for thou hast uncovered [thyself to another] than me, and hast gone up; thou hast (i) enlarged thy bed, and made thee [a covenant] with them; thou didst love their bed where thou sawest [it].
(h) Instead of setting up the word of God in the open places on the posts and doors to have it in remembrance, (Deuteronomy 6:9, Deuteronomy 27:1) you have set up signs and marks of your idolatry in every place.
(i) That is, increased your idolatry more and more.

Behind the doors also and the posts hast thou set up thy remembrance,.... The memorial of thine idols, as the Targum. As the Heathens had their "lares" and "penates", their household gods, so the Papists have their tutelar images, which they place in their houses, and in their bedchambers; their images of saints, their crucifixes and superstitious pictures, which they call "memories", and "laymen's books":
for thou hast discovered thyself to another than me; or, "from me" (n); departing from me, and leaving my bed; rejecting Christ as King of saints, deserting his worship and ordinances; thou hast uncovered thyself to another, prostituted thyself to another, been guilty of spiritual adultery or idolatry; receiving and acknowledging another for head of the church, according to whose will all things in worship are directed:
and art gone up; to the bed set up in the high place; to idolatrous temples and altars, there to offer sacrifice:
thou hast enlarged thy bed; to take in many adulterers, and idolatrous worshippers; and so, as Musculus observes, many small chapels, at first erected for this and the other saint, through the vast concourse of people to them, and the gifts they have brought, have, in process of time, become large and magnificent temples:
and made a covenant with them; with idols, and idol worshippers; agreeing to receive the mark and name of the beast, and to worship his image, Revelation 13:15, or, "thou hast cut for thyself more than they" (o); more trees to make idols of, or to make more room for the placing of idols in groves than the Heathens: or, "thou hast hewed it for thyself",
a bed larger (p) than theirs; that is, thy bed thou hast made larger than theirs: or, "thou hast cut for thyself from them" (q); taken away from emperors and kings part of, their dominions, and joined them to thy patrimony, and appropriated them to thine own use:
thou lovedst their bed where thou sawest it; took delight and pleasure in places of idolatrous worship, and in their idolatry, wherever they were: or, "thou lovedst their bed, a hand thou hast seen" (r); stretched out to help thee, or give thee power, or to invite, encourage, and receive thee into the idolatrous bed; or rather any pillar, monument (s), or statue, erected for idolatry, which seen, they fell down to and worshipped.
(n) "a me", Pagninus, Montanus, Junius & Tremellius, Piscator, Vitringa. (o) "et caedis tibi arbores plusquam illi", Piscator. (p) "Caedens tibi amplius Cubile quam illorum sit", Junius & Tremellius. (q) "Et excidisti tibi ex eis", Montanus. (r) "manum vidisti", Montanus, Cocceius. (s) "Ubi monumentum vidisti", Vitringa.

"Remembrance," that is, memorials of thy idolatry: the objects which thou holdest in remembrance. They hung up household tutelary gods "behind the doors"; the very place where God has directed them to write His laws "on the posts and gates" (Deuteronomy 6:9; Deuteronomy 11:20); a curse, too, was pronounced on putting up an image "in a secret place" (Deuteronomy 27:15).
discovered thyself--image from an adulteress.
enlarged . . . bed--so as to receive the more paramours.
made . . . covenant--with idols: in open violation of thy "covenant" with God (Exodus 19:5; Exodus 23:32). Or, "hast made assignations with them for thyself" [HORSLEY].
thy bed . . . their bed--The Jews' sin was twofold; they resorted to places of idolatry ("their bed"), and they received idols into the temple of God ("thy bed").
where--rather, "ever since that" [HORSLEY]. The Hebrew for "where" means "room" (Margin), a place; therefore, translate, "thou hast provided a place for it" (for "their bed"), namely, by admitting idolatrous altars in thy land [BARNES]; or "thou choosest a (convenient) place for thyself" in their bed [MAURER] (Isaiah 56:5).

The posts - Behind the posts of the doors of thine house: where the Heathens placed their tutelar gods to whose protection they committed their houses, that so they might have their eyes and minds upon them, whensoever they went out or came in. Set up - Those monuments which thou didst set up there as remembrances of those idol - gods whom they represented. Discovered - Thou hast uncovered thy nakedness; to others beside me thine husband. Gone up - Into the adulterous bed. Enlarged - That it might receive many adulterers together. Thou hast multiplied thine idols and altars. A covenant - Thou hast covenanted to serve them.
