Yes and i agree with sconzey on this one, you are taking a modern meaning of the word fornication without looking at the origonal text.
until you're able to deal with those other verses as it relates to the issue we don't have much to talk about, i s'ppose. i'm not interested in a debate for the sake of debating as it drives this thread completely offtopic and does nothing to help the OP. But it should be rather clear: sex
before marriage
is sex
outside marriage
. It all equals fornication (a perversion of the purpose of sex - 1 Cor 7) if you have not made that marital covenant and followed the laws of the land regarding marriage. Looking for loopholes isn't going to help you much in the long run, that just ensures you'll wind up in legalism.
as for Isaac, the Bible doesn't say they jumped into the sack and were married just because they had sex. reading into the passage what you want to see is called eisegesis and always leads to faulty theology. If you want to build an argument from any given passage you have to build it from the context, rather than a prooftext, which does not support what you're saying.
66 Then the servant told Isaac all he had done. 67 Isaac brought her into the tent of his mother Sarah, and he married Rebekah. So she became his wife, and he loved her; and Isaac was comforted after his mother's death. - NIV
66 And the servant told Isaac all the things that he had done. 67 Then Isaac brought her into his mother Sarah’s tent; and he took Rebekah and she became his wife, and he loved her. So Isaac was comforted after his mother’s
death. - NKJV
66 The servant told Isaac everything that had happened.67 Then Isaac brought Rebekah into the tent of Sarah, his mother, and she became his wife. Isaac loved her very much, and so he was comforted after his mother's death. - NCV
etc...
When Lots daughters got him drunk to have sex with him i doubt very much that meant they both married him.
but thats all i'm going to say on the matter now as, like i said, i have no interest in debating for the sake of debating
