'Yourselves' in the Bible

Come, you rulers of Israel, you who gave yourselves freely among the people: give praise to the Lord.

Then they said to him, We have come down to take you and give you up into the hands of the Philistines. And Samson said to them, Give me your oath that you will not make an attack on me yourselves.

And when their fathers or their brothers come and make trouble, you are to say to them, Give them to us as an act of grace; for we did not take them as wives for ourselves in war; and if you yourselves had given them to us you would have been responsible for the broken oath.
