'Relations' in the Bible

Then his father and mother said to him, Is there no woman among the daughters of your relations or among all my people, that you have to go for your wife to the Philistines, who are without circumcision? But Samson said to his father, Get her for me, for she is pleasing to me.

And this is what you are to do: every male, and every woman who has had sex relations with a man, you are to put to the curse, but you are to keep safe the virgins. And they did so.

Now there were among the people of Jabesh-gilead four hundred young virgins who had never had sex relations with a man; these they took to their tents in Shiloh in the land of Canaan.
