But above all, my brethren, do not swear, either by heaven or by earth or with any other oath. But let your “Yes” be “Yes,” and your “No,” “No,” lest you fall into judgment.

But I say to you, do not swear at all: neither by heaven, for it is God’s throne; nor by the earth, for it is His footstool; nor by Jerusalem, for it is the city of the great King.
But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.
