"Your pleasures": God does not intend that the Sabbath be a day of rigorous abstinence. In verse 14, He says that, if we keep it rightly, the day is going to be a delight. Rigorous abstinence is never a delight, but the Sabbath can be a delight.
The word "pleasure" is not wrongly translated, but it is somewhat misleading. Within the context, its intent is better translated "business," "desire," "purpose," or "matter." It describes what one finds pleasure in occupying himself in doing.
A man's business can be his pleasure. Some people just love to work! A person's pleasure might be riding a bicycle, yet the Sabbath is not a day to be out riding a bicycle the way he would like to ride a bicycle. What He's generally talking about are the things that normally keep us busy during the other six days.
The emphasis here is on the word "your," as in "your pleasure." It could refer to hobbies, sports, and entertainments. The Sabbath is not designed for swimming, jogging, hunting, fishing, TV, boating, woodworking, ham radios, raking leaves, stamp collecting—or whatever it is that we do to preserve our physical life. I have listed these because I have had questions on all of them.
I have known people who say they just love to rake leaves. So, when the leaves fall down to the ground in the autumn, they like to get out there and rake! They smell wood fires burning in the neighborhood, and that smoke is so nice and relaxing, so energizing. It makes them feel so good to get out there and rake the leaves. But the Sabbath was not designed for raking leaves. This would fall under the category of "your pleasure."
Now, is there anything wrong with raking leaves the other six days of the week? Of course not! Neither is there anything wrong with sports, entertainments, and those sorts of things as well—as long as they are not being done sinfully. But all of those things that we would tend to do on the other six days of the week, things that are "your pleasure," are not good uses of Sabbath time.
