Ecclesiastes 5:4-7

Living Bible

⁴ So when you talk to God and vow to him that you will do something, don’t delay in doing it, for God has no pleasure in fools. Keep your promise to him. ⁵ It is far better not to say you’ll do something than to say you will and then not do it. ^6-7 In that case, your mouth is making you sin. Don’t try to defend yourself by telling the messenger from God that it was all a mistake to make the vow.^[a] That would make God very angry; and he might destroy your prosperity. Dreaming instead of doing is foolishness, and there is ruin in a flood of empty words; fear God instead.
