'Selfish' in the Bible

They lament, 'Why don't you notice when we fast? Why don't you pay attention when we humble ourselves?' Look, at the same time you fast, you satisfy your selfish desires, you oppress your workers.

You must observe the Sabbath rather than doing anything you please on my holy day. You must look forward to the Sabbath and treat the Lord's holy day with respect. You must treat it with respect by refraining from your normal activities, and by refraining from your selfish pursuits and from making business deals.
