Oaths

Passage	New International Version
Mathew 5:33-37	Again, you have heard that it was said to the people long ago, 'Do not break your oath, but keep the oaths you have made to the Lord. But I tell you, Do not swear at all: either by heaven, for it is God's throne; or by the earth, for it is his footstool; or by Jersusalem, for it is the city of the Great King. And do not sear by your head, for you cannot make even one hair white or black. Simply let your 'Yes' be 'Yes,' and your 'No,' 'No'; anything beyond this comes from the evil one.
James 5:12	Above all, my brothers, do not swear--not by heaven or by earth or by anything else. Let your "Yes" be yes, and your "No," no, or you will be condemned.
