The strange woman is in the physical and spiritual. In the spiritual, the strange woman is false doctrine, false church, spiritualism, idolatry; and the whore just as in the physical. Both are adultery against God. Let that sink in.
Ecclesiastes 7:26 And I find more bitter than death the woman, whose heart is snares and nets, and her hands as bands: whoso pleaseth God shall escape from her; but the sinner shall be taken by her.
Proverbs 5:3-6 KJV
 For the lips of a strange woman drop as an honeycomb, and her mouth is smoother than oil:  But her end is bitter as wormwood, sharp as a twoedged sword.  Her feet go down to death; her steps take hold on hell.  Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them.
Proverbs 5:15-19 KJV
 Drink waters out of thine own cistern, and running waters out of thine own well.  Let thy fountains be dispersed abroad, and rivers of waters in the streets.  Let them be only thine own, and not strangers’ with thee.  Let thy fountain be blessed: and rejoice with the wife of thy youth.  Let her be as the loving hind and pleasant roe; let her breasts satisfy thee at all times; and be thou ravished always with her love.
Proverbs 5:20-23 KJV
 And why wilt thou, my son, be ravished with a strange woman, and embrace the bosom of a stranger?  For the ways of man are before the eyes of the Lord, and he pondereth all his goings.  His own iniquities shall take the wicked himself, and he shall be holden with the cords of his sins.  He shall die without instruction; and in the greatness of his folly he shall go astray.
Proverbs 7:24-27  Hearken unto me now therefore, O ye children, and attend to the words of my mouth.  Let not thine heart decline to her ways, go not astray in her paths.  For she hath cast down many wounded: yea, many strong men have been slain by her.  Her house is the way to hell, going down to the chambers of death.
Proverbs 23:27-35 KJV
 For a whore is a deep ditch; and a strange woman is a narrow pit.  She also lieth in wait as for a prey, and increaseth the transgressors among men.  Who hath woe? who hath sorrow? who hath contentions? who hath babbling? who hath wounds without cause? who hath redness of eyes?  They that tarry long at the wine; they that go to seek mixed wine.  Look not thou upon the wine when it is red, when it giveth his colour in the cup, when it moveth itself aright.  At the last it biteth like a serpent, and stingeth like an adder.  Thine eyes shall behold strange women, and thine heart shall utter perverse things.  Yea, thou shalt be as he that lieth down in the midst of the sea, or as he that lieth upon the top of a mast.  They have stricken me, shalt thou say, and I was not sick; and they have beaten me, and I felt it not: when shall I awake? I will seek it yet again.
Revelation 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
