'Handmaids' in the Bible

Then David returned to bless his household. And Michal the daughter of Saul came out to meet David, and said, How glorious was the king of Israel to-day, who uncovered himself to-day in the eyes of the handmaids of his servants, as one of the vain fellows shamelessly uncovereth himself!

And I will be yet more vile than this, and will be base in mine own sight: but of the handmaids of whom thou hast spoken, of them shall I be had in honor.
