How to knit purl knit in same stitch

Help, I am really lot here, this is new to me and i can’t get the stitch that the pattern calls for. Can someone explain how to knit purl knit in the same stitch. Thanks

Knit the stitch, don’t slip the original stitch off the left needle yet – now bring the yarn forward between the needles and purl the same stitch, still not slipping the original stitch off the left needle. Return the yarn to the back and knit the same stitch once more, now slipping the stitch off the left needle. You made 3 stitches onto the right needle.
