Hi wide eye girl, There are many scriptures in the Bible that pertain to marriage, for me I studied out the Proverbs 31 woman which is basically the wife of noble character and I love it, My husband and I have been married for 30 years, and a couple years ago we did the "Fire Proof" book together, it was great, God calls the men to treat their wives a certain way and the wives to treat their husbands a certain way so certain scriptures pertain to the husband and others to the wives, and of course some pertain to both.
Matthew 22:30, 24:38, Romans 7:2, and Hebrews 13:4 all pertain to marriage
Deuteronmy 24:5, Ezra 10:10, proverbs 30:23, Mathew 1:18, Mark 12:23, 1 Corernthians 7:27, 7:33, 7:36 All pertain to married
There's mre that pertains to husbands and to wives but I don't want to overwhelm you, Most couples study out what they need to work on in their marriage, their weaknesses, I man that's what we do and it works for us. I hope this helps you, feel free to send me a personal message and I can help you furthure. J.
