Binding off at either end of a garment?

I’m knitting a jumper at the moment and have just got up to the arm shaping. The pattern says to bind off six stitches at either end of the piece. How do you do this? do I bind it off the six stitches at the end and then cut the yarn and reattatch to continue knitting?

The BOs are on separate rows. You’ll BO 6 sts knitwise on the RS at the beginning of the row. When you’ve finished that row and turn your work to the WS, you’ll bind off the other 6 sts purlwise at the beginning of that row.
