Webster(i)
19 Then the chief captain took him by the hand, and went with him aside privately, and asked him, What is that thou hast to tell me?
20 And he said, The Jews have agreed to desire thee, that thou wouldst bring down Paul to-morrow into the council, as though they would inquire somewhat concerning him more perfectly.
21 But do not thou yield to them: for there are of them who lie in wait for him more than forty men, who have bound themselves with an oath, that they will neither eat nor drink till they have killed him: and now they are ready, looking for a promise from thee.
22 So the chief captain then let the young man depart, and charged him, See thou tell no man that thou hast shown these things to me.
