4 When you make a vow to God, do not delay to pay it; For He has no pleasure in fools. Pay what you have vowed— 5 Better not to vow than to vow and not pay. (Ecclesiastes 5:4–5, NKJV)
A vow is a solemn, voluntary promise made to God and to others. This reminder to swiftly pay a vow made to God is a rehearsal of the Law of Moses (Deuteronomy 23:21-23). The law explained to Israel that God required them to keep the vows they made to Him; failure to do so was sin. No doubt, that is reflected in God having “no pleasure in fools” (those who make vow but do not keep them). This foolish treatment of vows occurs when marriage vows are broken for the most dismissive reasons. “Irreconcilable differences” is often legal code for “I don’t want to be married to this person anymore.” If you are married, you vowed yourself to your spouse before God and witnesses to be joined in marriage “for better and for worse, for richer or poorer, in sickness and in health, forsaking all others, until death we do part.” With such vows made in a God-approved marriage, He binds the husband and wife to each other for life (Malachi 2:14; Matthew 19:4-6; Romans 7:2-3). Take your vows seriously; God does. Keep your vows swiftly. God does not favor fool who do not keep their vows.
