How to bind off a scarf in pattern?

It says to bind off in pattern which says seed 5 purl k6 p1seed7 p1k6 p1 end seed5. I only know how to normal bind off but not in this pattern . Please help.

What you’ll be doing to bind off in pattern is to bind off purlwise on purls and knitwise on knits. A “normal” bind off is usually done knitwise.
