Urgent! Can someone give me some idea of a nice wedding wish in portuguese for a brazilian wedding? - wording for congratulation on wedding

Hello,
My friend married a Brazilian girl, and I am his best man.
I need to make a speech at the wedding and wanted to take a few nice words in Portuguese to wish them good luck for two.
Can anyone help please send me a good sentence or two into Portuguese too? (Bonus if you could help with pronunciation)

Please traditional greeting comes to mind, you can translate the following?
"Congratulations on your marriage! On May the honeymoon last forever"

Thank you!
