'Yes' in the Bible

Abner turned around and said, "[Are] you this Asahel?" And he said, "Yes."

The king asked, "[Was] the hand of Joab with you in all of this?" The woman answered and said, "{As your soul lives}, my lord the king, surely [one cannot] go to the right or to the left from all that my lord the king has spoken. Yes, your servant Joab himself commanded me, and he put all of these words in the mouth of your servant.
