'Keep' in the Bible

He struck Moab, and measured them with the line, making them to lie down on the ground; and he measured two lines to put to death, and one full line to keep alive. The Moabites became servants to David, and brought tribute.

The king went forth, and all his household after him. The king left ten women, who were concubines, to keep the house.

Ahithophel said to Absalom, "Go in to your father's concubines, that he has left to keep the house. Then all Israel will hear that you are abhorred by your father. Then the hands of all who are with you will be strong."

Now Absalom in his lifetime had taken and reared up for himself the pillar, which is in the king's dale; for he said, "I have no son to keep my name in memory." He called the pillar after his own name; and it is called Absalom's monument, to this day.

David came to his house at Jerusalem; and the king took the ten women his concubines, whom he had left to keep the house, and put them in custody, and provided them with sustenance, but didn't go in to them. So they were shut up to the day of their death, living in widowhood.
