Paraphrase
These are the ones who have not been defiled with women, for they are pure. These are the ones who follow THE ONLY EFFICACIOUS SACRIFICE wherever He goes. These have been redeemed from among men and are totally committed, and therefore are very pleasing
to THE CREATOR AND OWNER OF ALL THINGS and to THE ONLY EFFICACIOUS SACRIFICE.
