Numbers chapter 30 verse 2 says, If a man makes a vow to the Lord or takes an oath to bind himself with a binding obligation, he shall not violate his word. He shall do according to all that proceeds out of his mouth. Vows were voluntary promises to do or not do specified things. Some vows were offered to express thanks when God had done something special. A vow was a required obligation not to be broken, but fulfilled completely. Chapter 30 explains the important principle that one should not regard self-imposed religious obligations as more important than God-given callings. Sometimes we make an unwise vow to God. Later, we may realize that that vow is keeping us from obeying the Lord. In such cases, we should ask God to forgive us for this unwise vow and obedience to God should outweigh keeping a vow. Since the basis of faith is believing and knowing that God is completely trustworthy, we need to make sure we fulfill our vows to do God's will. Amen.
