'Certain' in the Bible

Now a certain woman of the wives of the sons of the prophets cried out to Elisha, “Your servant my husband is dead, and you know that your servant feared the Lord; and the creditor has come to take my two children to be his slaves.”

When the king asked the woman, she related it to him. So the king appointed for her a certain officer, saying, “Restore all that was hers and all the produce of the field from the day that she left the land even until now.”
