'Ten' in the Bible

So the king left, taking his entire household with him except for ten mistresses, who were to keep the palace in order.

Joab asked the man who was reporting to him, "What! You saw him? Why didn't you kill him right then and there? I would've given you ten pieces of silver and a warrior's sash!"

Ten young men who served as Joab's personal assistants then surrounded Absalom, striking him repeatedly and killing him.

But the men from Israel answered the men from Judah: "We represent ten of the tribes of Israel! So we have more right to David than you do! Why haven't you taken us seriously? Weren't we the first to talk about bringing back our king?" But what the people of Judah had to say was harsher than what the people of Israel were saying.

When David arrived at his palace in Jerusalem, the king took the ten mistresses whom he had left behind to keep the palace in order and placed them in a separate house, providing for them under the care of a protective guard. He never visited them again, so they were under care until they died, living as if their husbands had died.
