Leviticus is clear in its meaning.
Leviticus 20:13
13 If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
It speaks on adultery here.
Leviticus 20:10-11
10 And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death.
11 And the man that lieth with his father's wife hath uncovered his father's nakedness: both of them shall surely be put to death; their blood shall be upon them.
You will want to read Leviticus chapter 20 again to get a more complete picture but specifically 20:9-21
He says to keep his commandments here 20:7-8, 22-24 in that chapter.
Romans is clear also
Romans 1:24-32
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
It clearly states that ALL of these things are worthy of death, and that those who accept these things and think them good are also worthy of death.
Here again the same.
1 Corinthians 6:9-11
9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
Corinthians talks on fornication specifically in that chapter here.
1 Corinthians 6:15-20
15 Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid.
16 What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh.
17 But he that is joined unto the Lord is one spirit.
18 Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.
19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
All sins are equal in the sight of the Lord God Yahweh, then homosexuality (along with every other sin) is a sin worthy of death and damnation under the Law.
1 John 3:4
4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
James 2:9-13
9 But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.
10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
12 So speak ye, and so do, as they that shall be judged by the law of liberty.
13 For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment.
