Mathew 5:33-36
“You have also heard that people were told in the past , Do not break your promise, but do what you have vowed to the Lord to do. But now i tell you, do not use any vow when you make a promise. Do not swear by heaven for it is God’s throne, nor by earth for it is the resting place for his feet , nor by King . Do not even swear by your head, because you cannot make a single hair white or black. Just say Yes or No anything you say comes from the Evil One.
May the LORD bless his word, Amen.
