do not swear: The churches were having serious arguments (4:1–3, 11–12), so James advised them to avoid dishonest oaths by not using any oaths at all (Matt 5:33–37). Swearing an oath in the Lord's name meant asking God to enforce it (Genesis 31:53; 1 Kings 8:31–32). People swore by heaven or earth. They either pretended to be respectful while avoiding speaking God's name or used tricky words to deceive (Matthew 23:16–22). Peter used an oath dishonestly (Matthew 26:71–73). But Paul used one to support his claims (Romans 1:9; 2 Corinthians 1:23). This indicates that the rule against oaths is not absolute.
