You confuse the terms of our today society with the rules of God,
Deuteronomy 21:18 "If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and that, when they have chastened him, will not hearken unto them:"
Deuteronomy 21:19 "Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;"
Deuteronomy 21:20 "And they shall say unto the elders of his city, `This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard.' "
Deuteronomy 21:21 "And all the men of his city shall stone him with stones, that he die: so shalt thou put evil away from among you; and all Israel shall hear, and fear."
I will let Torah define minor momentarily. However, the verses you posted above
may not apply to a "minor" committing adultery. Seduction can be very powerful.
Now then, who is defined as an Adult?
Exodus 30:14Every one that passeth among them that are numbered, from
twenty years old and above, shall give an offering unto the LORD. 15The rich shall not give more, and the poor shall not give less than half a shekel, when they give an offering unto the LORD,
to make an atonement for your souls.
Numbers 1: 3From twenty years old and upward, all that are able to go forth to war in Israel: thou and Aaron shall number them by their armies.
Numbers 14:
28Say unto them, As truly as I live, saith the LORD, as ye have spoken in mine ears, so will I do to you:
29Your carcases shall fall in this wilderness; and all that were numbered of you, according to your whole number, from twenty years old and upward which have murmured against me.
30Doubtless ye shall not come into the land, concerning which I sware to make you dwell therein, save Caleb the son of Jephunneh, and Joshua the son of Nun.
31But your little ones, which ye said should be a prey, them will I bring in, and they shall know the land which ye have despised.
32But as for you, your carcases, they shall fall in this wilderness.
33And your children shall wander in the wilderness forty years, and bear your whoredoms, until your carcases be wasted in the wilderness.
Thus, we can clearly see the age of 20 as a defining line.
With that, a man is defined by scripture as one 20 years old or older.
Leviticus 20:10
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.
