'Servant girl' in the Bible

and every firstborn male in the land of Egypt will die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the servant girl who is behind the millstones, as well as every firstborn of the livestock.

Jonathan and Ahimaaz were staying at En-rogel, where a servant girl would come and pass along information to them. They in turn would go and inform King David, because they dared not be seen entering the city.

Like a servant’s eyes on his master’s hand,like a servant girl’s eyes on her mistress’s hand,so our eyes are on the Lord our Goduntil He shows us favor.
