'Refrain' in the Bible

Do not carry a money belt, a provision bag, or [extra] sandals; and do not greet anyone along the way [who would delay you].

Or is it only Barnabas and I who have no right to stop doing manual labor [in order to support our ministry]?

Then I fell down at his feet to worship him, but he [stopped me and] said to me, “You must not do that; I am a fellow servant with you and your brothers and sisters who have and hold the testimony of Jesus. Worship God [alone]. For the testimony of Jesus is the spirit of prophecy [His life and teaching are the heart of prophecy].”

But he said to me, “Do not do that. I am a fellow servant with you and your brothers the prophets and with those who heed and remember [the truths contained in] the words of this book. Worship God.”
