 Some religious groups or sects like the Mennonites and the Quakers or Jehovah's Witnesses have read Jesus' words in that way. It's wrong to take an oath in court or an oath in some other context. But if you read the rest of the New Testament, it's clear that the followers of Jesus, the apostles of our Lord, oftentimes would make vows or invoke God's name. And so it doesn't seem like that's what's happening here. It's not this just sort of blanket condemnation of making an oath.
