Nice try, but not quite. There are 10 different words translated "lust" in the New Testament, and only one of them can mean simple desire. Click on the word and you will not only see the definition but also the list of uses and in which books.
Again, for the reasons listed above, false. Also false. The context includes all women, not just married women.And again, false. This is a Hebrew idiom, the word used of those who at a woman's solicitation are drawn away to idolatry, literally to the eating of things sacrificed to idols but metaphorically all things coming between a man and God are idols. That includes illicit sex of any kind.Proof please. Otherwise this looks like a pathetic effort to justify sin. Which it is.
Methinks the man doth protest too much.
The central issue is what Greek word is used in Matt 5:28, not what other Greek words may be used elsewhere, or how each was translated.
The Greek word used in this verse is epithumeo. That word is used 16 times in the NT.
Matthew 5:28 But I say unto you, That whosoever looketh on a woman to
lust after her hath committed adultery with her already in his heart.
Matthew 13:17 For verily I say unto you, That many prophets and righteous men
have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.
Luke 15:16 And he
would fain have filled his belly with the husks that the swine did eat: and no man gave unto him.
Luke 16:21 And
desiring to be fed with the crumbs which fell from the rich man's table: moreover the dogs came and licked his sores.
Luke 17:22 And he said unto the disciples, The days will come, when ye
shall desire to see one of the days of the Son of man, and ye shall not see it.
Luke 22:15 And he said unto them,
With desire I have desired to eat this passover with you before I suffer:
Acts 20:33 I
have coveted no man's silver, or gold, or apparel.
Romans 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou
shalt not covet.
Romans 13:9 For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not
covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.
1 Corinthians 10:6 Now these things were our examples, to the intent we should
not lust after evil things, as they also
lusted.
Galatians 5:17 For the flesh
lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
1 Timothy 3:1 This is a true saying, If a man desire the office of a bishop, he
desireth a good work.
Hebrews 6:11 And
we desire that every one of you do shew the same diligence to the full assurance of hope unto the end:
James 4:2 Ye
lust, and have not: ye kill, and desire to have, and cannot obtain: ye fight and war, yet ye have not, because ye ask not.
1 Peter 1:12 Unto whom it was revealed, that not unto themselves, but unto us they did minister the things, which are now reported unto you by them that have preached the gospel unto you with the Holy Ghost sent down from heaven; which things the angels
desire to look into.
Revelation 9:6 nd in those days shall men seek death, and shall not find it; and shall
desire to die, and death shall flee from them.
On your second point adultery refers only to someone who is married. The context is interesting too. There is a section in law keeping, beginning with
Matt 5:17-18 Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. We then see Jesus challenging them on their traditions as misrepresenting the true spirit of the law, which Jesus exposes in four places 5:27,33, 38 7 43, each beginning with the words "You have heard.."
The pericopes beginning at v 27 and 33 are related. Both push the Pharisees further into their duplicity regarding divorce and remarriage. Adultery is right at the centre of Jesus teaching with the male religious leaders squarely in His sights.
