Matthew 5:34
I, however, say to you that you must not swear at all, either by Heaven, since that is God's throne,
James 5:12
Above all things, my Brothers, never take an oath, either by heaven, or by earth, or by anything else. With you let 'Yes' suffice for yes, and 'No' for no, so that you may escape condemnation.
Matthew 23:16-22
Alas for you, you blind guides! You say 'if any answer by the Temple, his oath counts for nothing; but, if any one swears by the gold of the Temple, his oath is binding him'!
