51 Watch your step when you enter God's house. Enter to learn. That's far better than mindlessly offering a sacrifice, Doing more harm than good. 2 Don't shoot off your mouth, or speak before you think. Don't be too quick to tell God what you think he wants to hear. God's in charge, not you - the less you speak, the better. 3 Over-work makes for restless sleep. Over-talk shows you up as a fool.
4 When you tell God you'll do something, do it - now. God takes no pleasure in foolish gabble. Vow it, then do it. 5 Far better not to vow in the first place than to vow and not pay up. 6 Don't let your mouth make a total sinner of you. When called to account, you won't get by with "Sorry, I didn't mean it." Why risk provoking God to angry retaliation?

Commentary on Ecclesiastes 5:1-3
(Read Ecclesiastes 5:1-3)
Address thyself to the worship of God, and take time to compose thyself for it. Keep thy thoughts from roving and wandering: keep thy affections from running out toward wrong objects. We should avoid vain repetitions; copious prayers are not here condemned, but those that are unmeaning. How often our wandering thoughts render attendance on Divine ordinances little better than the sacrifice of fools! Many words and hasty ones, used in prayer, show folly in the heart, low thoughts of God, and careless thoughts of our own souls.
Commentary on Ecclesiastes 5:4-8
(Read Ecclesiastes 5:4-8)
When a person made engagements rashly, he suffered his mouth to cause his flesh to sin. The case supposes a man coming to the priest, and pretending that his vow was made rashly, and that it would be wrong to fulfil it. Such mockery of God would bring the Divine displeasure, which might blast what was thus unduly kept. We are to keep down the fear of man. Set God before thee; then, if thou seest the oppression of the poor, thou wilt not find fault with Divine Providence; nor think the worse of the institution of magistracy, when thou seest the ends of it thus perverted; nor of religion, when thou seest it will not secure men from suffering wrong. But though oppressors may be secure, God will reckon for all.
