NET

21 So do not let them persuade you to do this, because more than forty of them are lying in ambush for him. They have bound themselves with an oath not to eat or drink anything until they have killed him, and now they are ready, waiting for you to agree to their request.”

Darby

21 Do not thou then be persuaded by them, for there lie in wait for him of them more than forty men, who have put themselves under a curse neither to eat nor drink till they kill him; and now they are ready waiting the promise from thee.

KJV

21 But do not thou yield unto them: for there lie in wait for him of them more than forty men, which have bound themselves with an oath, that they will neither eat nor drink till they have killed him: and now are they ready, looking for a promise from thee.
