'Dress' in the Bible

Blessed [are] those slaves whom the master will find on the alert [when he] returns! Truly I say to you that he will dress himself for service and have them recline at the table and will come by [and] serve them.

Will he not rather say to him, 'Prepare something that I may eat, and dress yourself to serve me while I eat and drink, and after these [things] you will eat and drink.'
