not understanding a section in a pattern

row 4 states K2, * with yarn in front, slip next stitch purl wise, bring yarn to back, slip next stitch purl wise, pass, second stitch on the right needle over the first, slip the first stitch on the right needle to the left needle, turn work, bring yarn to back, using a cable cost on (cast of 3sts) turn work ,bring yarn to back, slip first stitch on left needle to the right needle, pass the second stitch on the right needle over the first, *knit to the last 4 stitches, repeat from **, K1
What does all this mean?

That does sound confusing. I think I have it in my head, but not sure. Can you please tell us the name of the pattern and provide a link if possible? Don’t post the pattern because of copyright rules.
