Jesus ordered him to tell no one [that he might happen to meet], “But go and show yourself to the priest, and make an offering for your purification, just as Moses commanded, as a testimony (witness) to them [that this is a work of Messiah].”

But He strictly warned and admonished them not to tell this to anyone,

John replied, “Master, we saw someone driving out demons in Your name; and we tried to stop him because he does not follow along with us.”

And the servant [after returning] said, ‘Sir, what you commanded has been done, and still there is room.’

So you too, when you have done everything that was assigned and commanded you, say, ‘We are unworthy servants [undeserving of praise or a reward, for we have not gone beyond our obligation]; we have merely done what we ought to do.’”
