51 Keep thy feet when thou goest unto a house of God, and draw near to hear rather than to give of fools the sacrifice, for they do not know they do evil. 2 Cause not thy mouth to hasten, and let not thy heart hasten to bring out a word before God, for God is in the heavens, and thou on the earth, therefore let thy words be few. 3 For the dream hath come by abundance of business, and the voice of a fool by abundance of words.
4 When thou vowest a vow to God, delay not to complete it, for there is no pleasure in fools; that which thou vowest—complete. 5 Better that thou do not vow, than that thou dost vow and dost not complete. 6 Suffer not thy mouth to cause thy flesh to sin, nor say before the messenger, that 'it 'is' an error,' why is God wroth because of thy voice, and hath destroyed the work of thy hands?
Matthew Henry's Commentary on Ecclesiastes 5:1-6
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.
