¹² And you shall not swear by My name falsely, neither shall you profane the name of your God. I am the Lord.

² If a man vows a vow to the Lord or swears an oath to bind himself by a pledge, he shall not break and profane his word; he shall do according to all that proceeds out of his mouth.

²¹ When you make a vow to the Lord your God, you shall not be slack in paying it, for the Lord your God will surely require it of you, and slackness would be sin in you.
